Effects of Anchimeric Assistance in Phosphonium Enolates Chemistry

摘要

Phosphonium enolates are key intermediates of phosphine-catalyzed reactions extensively used in current organic synthesis for construction of carbon-carbon and carbon-heteroatom bonds. Herein, general methods for increasing the rates, chemo- and stereoselectivity on the basis of effects of anchimeric assistance for the reactions involving formation of phosphonium enolates are discussed.
