hydrometalations, and many others. The discovery of Lewis and Brønsted acid catalyzed manifolds recently, has opened new doors for further development of this important reaction. This book provides an up-to-date, comprehensive survey of the literature of this rich chemistry as it pertains to organic synthesis. Consistent with the goal of Organic Reactions, the content and presentation emphasize the preparative aspects of the reactions, giving considerable attention to the scope and limitations of the individual transformations along with detailed experimental procedures. A tabular survey of all examples of carbonyl allylboration used in organic synthesis is presented in nine tables organized by type of allylic boron reagent with listings within each table according to increasing carbon number of the carbonyl substrates. The literature is covered through December 2010, including a new listing of nearly 200 literature citations that supplement the original coverage of 834 references used in the earlier hard cover version of the chapter. Allylboration of Carbonyl Compounds is intended to be a useful, easily read reference book for all practitioners of synthetic organic chemistry working in academic and industrial laboratories.
