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.

Mechanochemical treatment is one of the modern promising directions of the chemical and technological processes of obtaining a new substance as a result of the transformation of mechanical energy into the chemical and physical processes of system restructuring. This book presents years of research on the mechanochemical synthesis of composite systems, consisting of inorganic and organic components, obtained by the scientific team of the Institute of Combustion Problems. The book contains, first of all, general ideas about the mechanochemical process and the phenomena accompanying it. The main provisions of structural rearrangement and modification of the surface of dispersible particles are considered, as well as thermodynamics of mechanochemical treatment of materials. Then, using the example of a number of natural minerals, it is shown how mechanochemical treatment can radically change their structure and properties, using various organic compounds as modifiers. Particular attention is paid to the use of ultrasonic treatment, as a kind of mechanical action in a liquid medium on a solid.

This book provides informative, useful, and stimulating reading on the topic of organic sonochemistry – the core of ultrasound-based applications. Given the increasing interest in new and improved technologies, allied to their green and sustainable character (not always a valid premise), there is a great attraction for organic chemists to apply these protocols in synthesis and process chemistry. Unfortunately, as with other enabling technologies, many researchers new to the field have received a simple and dishonest message: just switch on! Therefore a significant portion of sonochemical syntheses lack reproducibility (surprisingly cavitation control and/or ultrasonic parameters are omitted) and the actual role of sonication remains uncertain. While this book does not provide a detailed description of fundamentals, the introductory remarks highlight the importance of cavitational effects and their experimental control. It presents a number of concepts of sonochemical reactivity and empirical rules with pertinent examples, often from classical and recent literature. It then focuses on scenarios of current interest where organic chemistry, and synthesis in particular, may benefit from sonication in terms of both chemical and mechanical activation. The “sustainable corner” of this field is largely exemplified through concepts like atom economy, renewable sources, wasteless syntheses, and benign solvents as reaction media. This book is useful for both researchers and graduate students, especially those familiar with the field of sonochemistry and applications of ultrasound in general. However, it is also of interest to a broader audience as it discusses the fundamentals, techniques, and experimental skills necessary for scientists wishing to initiate the use of ultrasound in their domain of expertise.

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.
