This much-needed resource brings together a wealth of procedures for the synthesis and practical use of diazocarbonyl compounds. It features methods for the preparation of important catalysts and for applications of diazocarbonyl compounds within each of the main transformation categories-including in-depth coverage of cyclopropanation, C-H and X-H insertion, Wolff rearrangement, ylide formation, aromatic cycloaddition and substitution, and many other useful reactions. Written by leading experts in the field, this book contains cutting-edge material on highly enantioselective transformations, and presents new ways of thinking about diazocarbonyl compounds and their applications, from donor-acceptor cyclopropanes in organic synthesis to macrocyclic cyclopropanation. Complete with illustrative examples of procedures in each chapter, clear diagrams, and a detailed bibliography, this practical reference gives readers the tools they need to put diazocarbonyl compounds to work for their own projects-an invaluable source of guidance for synthetic organic chemists, chemical scientists, and advanced students.

The book is the outcome of a unique venture: a team of Chinese geographers and a team of American geographers collaborated on a new Comparative Geography of China and the United States. The book meets a high demand for comparative information about China and the United States, as the home of the two leading economies in a globalizing world. Comparisons of the two countries include the similarities and differences in their physical environments and natural hazards, the growth and changing spatial distribution of population and ethnic groups in China and the U.S., traditions and contemporary regional expressions of agriculture and food production as well as the rapidly changing urban and industrial patterns in both countries. The book also highlights the two countries’ interconnectedness, in trade and in the exchange of cultural, social, scientific & technological information. The volume serves as a major resource in geographic education as it contributes to a better and more comprehensive understanding of the formation and development of the two countries’ basic geographical patterns and processes.
