Authors


Abstract

The design of a catalytic manifold for the Wittig reaction is highlighted. Arsenine-, telluride-, and the recently discovered phosphine-catalyzed processes are discussed and placed into context with the related silyl-Reformatsky process. The specific type of phosphine oxide precatalyst employed is compared with an aza-Wittig process and related transformations.
