The most comprehensive and highly focused treatment of important organic reactions currently available, this series represents an important addition to chemistry libraries in both academic and industrial settings, and is a valuable resource for both students and professionals in the field. Volume 61 contains two chapters: "[3 + 2] Cycloaddition of Trimethylenemethane and its Synthetic Equivalents," by Shigeru Yamago and Eiichi Nakamura, and "Dioxirane Epoxidation of Alkenes," by Waldemar Adam, Chantu R. Saha-Möller, and Cong-Gui Zhao. Organic Reactions is a comprehensive series devoted to important synthetic reactions, each volume having wide applicability. Each chapter focuses on a single reaction or a definitive phase of a reaction, and each is written by world-renowned chemists with extensive hands-on experience in their specialties. The material is presented from a preparative point of view, and particular attention is given to reaction limitations, interfering influences, effects of chemical structure, and the selection of experimental conditions. Each reaction includes information about its conditions, products, and yields, where available, and is fully referenced to the primary literature. The authors also include detailed procedures illustrating the significant modifications of the chemical reaction, as well as tables featuring all pertinent data about the reaction.
