The demand for increasingly clean and efficient chemical syntheses is continuously becoming more urgent from both an economic and an environmental standpoint. So-called green technologies are looking for alternatives, yet they focus on large quantities of hazardous even toxic solvents. One could even say that the best solvent is no solvent. It is against this background that chemical synthesis without the use of solvents has increasingly developed into a powerful methodology. Once the chemical reactivity is increased, the amount of initial substances needed is reduced; in particular it removes the need for the complex recycling and disposal of solvents.In this book, the third in our open "Green Chemistry" series, Koichi Tanaka describes the latest developments in this exciting field. Packed with advice on applications, this will be equally useful to practitioners in research as well as process chemists in industry, such that it is sure to become an invaluable reference source.
