With the main theme of sustainability, this reference discusses methods for chemical synthesis that are more efficient and less energy intensive as traditional methods at room temperature or with added heat. This book contains chapters that not only give important representative examples of the techniques which have recently seen an uptake in synthetic chemistry, but also discusses the future development of each technique. Of interest to a broad audience, in particular those in fields related to alternative processing, this volume offers information on new ways to do chemistry that can be faster, easier, better, more efficient, and/or more selective.
