Mechanochemical Organic Synthesis is a comprehensive reference that not only synthesizes the current literature but also offers practical protocols that industrial and academic scientists can immediately put to use in their daily work. Increasing interest in green chemistry has led to the development of numerous environmentally-friendly methodologies for the synthesis of organic molecules of interest. Amongst the green methodologies drawing attention, mechanochemistry is emerging as a promising method to circumvent the use of toxic solvents and reagents as well as to increase energy efficiency. The development of synthetic strategies that require less, or the minimal, amount of energy to carry out a specific reaction with optimum productivity is of vital importance for large-scale industrial production. Experimental procedures at room temperature are the mildest reaction conditions (essentially required for many temperature-sensitive organic substrates as a key step in multi-step sequence reactions) and are the core of mechanochemical organic synthesis. This green synthetic method is now emerging in a very progressive manner and until now, there is no book that reviews the recent developments in this area. Features cutting-edge research in the field of mechanochemical organic synthesis for more sustainable reactions Integrates advances in green chemistry research into industrial applications and process development Focuses on designing techniques in organic synthesis directed toward mild reaction conditions Includes global coverage of mechanochemical synthetic protocols for the generation of organic compounds

Ball milling has emerged as a powerful tool over the past few years for effecting chemical reactions by mechanical energy. Allowing a variety of reactions to occur at ambient temperatures and in solvent-free conditions, ball milling presents a greener route for many chemical processes. Compared to the use of microwave and ultrasound as energy sources for chemical reactions, ball milling is not as familiar to chemists and yet it holds great potential. This book will introduce practicing chemists to the technique and will highlight its importance for green transformations. Current applications of ball milling will be covered in detail as well as its origin, recent developments and future scope, challenges and prospects. Chemical transformations covered include carbon-carbon and carbon-heteroatom bond formation, oxidation by solid oxidants, asymmetric organo-catalytic reactions, dehydrogenative coupling, peptide syntheses and polymeric material syntheses. The book will provide a valuable guide for organic, inorganic and organometallic chemists, material scientists, polymer scientists, reaction engineers and postgraduate students in chemistry.

Abstract : Mechanochemical knowledge and technology is leaving empiricism behind. What has been learned? And what secrets still remain in the blackbox? Abstract : Perhaps due in no small part to its historical mystique, mechanochemistry has been shrowded in relative obscurity for quite some time. The successes of mechanochemistry in organic synthesis have often been curtailed by a fundamentally limited mechanistic understanding. Lately, however, the community has made great strides towards understanding the fundamentals, as well as large steps forward regarding industrially significant scale-up via twin-screw extrusion. A variety of recent work has traded in some of mechanochemistry's mystique for simple, straight-forward chemical guidelines. This exchange eases the concerns of a would-be practitioner of mechanochemistry, interested in having another tool in their lab. Simultaneously, pressures on institutions and researchers regarding lab safety, environmental awareness, productivity, and so on, continue to make mechanochemistry particularly attractive. The demand has never been higher for a methodology addressing these pressures, and at the same time the barriers to adopting mechanochemistry have never been lower. That being said, there still remains some mystique guarding the "rules" of mechanochemistry. For those interested in solving these fundamental questions, there remain plenty of high-value targets, and several of these will feature throughout this review.

The 20th century has seen a phenomenal growth in the global economy and continuous improvement in the standard of living in the industrialized countries. Sustainable development has become an ideal target in recent years and in the early 1990s the concept of "Green chemistry" was launched in the USA as a new paradigm, and since 1993 it has been promoted by the National Science Foundation (NSF) and the Environmental Protection Agency (EPA). The success of the pharmaceutical industry is, in large part, due to the towering achievement of organic chemistry, a mature science which emerged as a distinct discipline well over 150 years ago, however this has been both a blessing and a curse. Many of our most reliable strategies for assembling target molecules employ reactions which are fifty to one hundred years old and are often named in honour of their discoverers. During these early years, the chronic toxicological properties of chemicals were often completely unknown and many unwittingly became indispensable tools of the trade. Early pioneers in green chemistry included Trost (who developed the atom economy principle) and Sheldon (who developed the E-Factor). These measures were introduced to encourage the use of more sustainable chemistry and provide some benchmarking data to encourage scientists to aspire to more benign synthesis. Green chemistry is essentially the design of chemical processes and procedures that reduce or eliminate the use, or the generation, of hazardous substances. Green chemistry is a growing area of research and an increasing number of researchers are now involved in this field. The number of publications has dramatically increased and new recognition of advances made is necessary with respect to other research areas. The synthesis of "Fine Chemicals" represents one of the main goals in organic synthesis and this new book extensively examines the main processes and procedures for their preparation under eco-friendly conditions. The book is a collection of selected research topics delivered by scientists involved in some of the more prominent fields of green chemistry. It is devoted to the synthesis of fine chemicals by the use of alternative eco-friendly solvents (ionic liquids, polyethylene glycol, water, etc.), supported organic catalysis, microwave irradiation or high pressure as contributors to more efficient processes, photochemistry as a green procedure and solvent-free processes. Each chapter gives an introduction to the various methods or procedures and their contribution to green chemistry and a variety of the most representative examples of the eco-friendly synthesis of fine chemicals are reported and discussed. In addition, there is a chapter dedicated to the application of simple reaction to the synthesis of complex molecules.The chapters are all written by authors who are experts in their field and are exhaustively referenced and the book will be invaluable for researchers and industrialists as well as academia.

The main goal in preparing this book was to publish contemporary concepts, new discoveries and innovative ideas in the field of surface engineering, predominantly for the technical applications, as well as in the field of production engineering and to stress some problems connected with the use of various surface processes in modern manufacturing of different purpose machine parts. This book is an attempt to introduce science into the study of surface treatment processes. Tribology offers a good approach for describing abrasive machining and coating processes and offers the ability to predict some of the outputs of the processes. The study of friction, forces, and energy explores the importance of the various factors which govern the stresses and deformations of abrasion. The effects of grain shape, depth of penetration, and lubrication on the process forces are explored. The tribology of nanostructured surfaces involves many fundamental and scientific issues. More importantly, it has tremendous applications in industries. It is a powerful tool to regulate friction, adhesion, and wetting of surfaces by altering their geometric textures and material compositions at the nanoscale, and, hence, to control the tribological performance of the engineering surfaces.

The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Review articles for the individual volumes are invited by the volume editors. Readership: research chemists at universities or in industry, graduate students.

Green Chemistry is an inventive science based on fundamental research towards the development of new sustainable chemical processes. There is a great need to create a new type of chemistry focused on a new production system, in order to prepare the younger generation to get a greener future. The globalization pushes the chemistry community to adopt ethical issues. In this prospect Green Chemistry can achieve the approval of the society by teaching students to be confident in science and at the same time by convincing people that it is possible to attain technological development with respect and care for the environment we live in. This is why it is of foremost importance that education and fundamental research remain strictly connected, so that democracy and development can grow and progress side by side. This book has been prepared to extend the knowledge of Green Chemistry not disregarding, however, the industrial interest. It is the result of the effort to put together and share the expertise of leading practitioners in the field of Green Chemistry. The Interuniversity Consortium ‘Chemistry for the Environment’ is a non-profit organisation established in 1993 in Italy. At present it includes 31 member universities and 80 research units.

This book connects a retrosynthetic or disconnection approach with synthetic methods in the preparation of target molecules from simple, achiral ones to complex, chiral structures in the optically pure form. Retrosynthetic considerations and asymmetric syntheses are presented as closely related topics, often in the same chapter, underlining the importance of retrosynthetic consideration of target molecules neglecting stereochemistry and equipping readers to overcome the difficulties they may encounter in the planning and experimental implementation of asymmetric syntheses. This approach prepares students in advanced organic chemistry courses, and in particular young scientists working at academic and industrial laboratories, for independently solving synthetic problems and creating proposals for the synthesis of complex structures.

Organochlorines (OC) are organic molecules with chlorine in their structure. There is a large number of organochlorine compounds known. Large amounts of chlorinated organic compounds are produced for industrial, agricultural, pharmaceutical, household purposes, etc. In many studies, the main focus is on OC that have been evaluated as environmental contaminants with toxic effects on humans. Different types of organochlorines have been produced throughout the world. Some of the most popular classes are organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), dioxins, chlorobenzenes, chlorophenols, chlorinated alkanes, etc. Organochlorine compounds are very stable. Generally, they are molecules of moderate polarity (low solubility in water). This makes OCs easily soluble in fats. They are found in almost all environments: air, water, soil, sediments and biota samples. They can spread out easily in different geographic altitudes and latitudes. Volatile and semi-volatile OCs have the ability to travel far distances from the place where they were used. Some studies have reported some organochlorines in the North Pole at the same levels as the areas where they were produced or applied. They have the ability to bioaccumulate easily in biota. Passing through the food chain levels, they increase their concentrations (biomagnifying). The main access pathways for OCs to the human body are through foods and exposures. Generally, they display their effects after a relatively long period of exposure. This is the main reason why they were produced and used for a long time before their production and use was banned. The most important health effects that organochlorines can cause are: mutagenic, endocrine-disruptor, carcinogenic and central nervous or peripheral disorders. After identification of the consequences, production of OCs and use was banned in many countries but their effects are still being seen many years later.
