The One-Pot Palladium Catalyzed Wittig Reaction with Allylic Alcohols. Scope and Limitations

Abstract
Some allylic alcohols react with aldehydes and triphenylphosphine in a one-pot formal Wittig reaction under Pd° catalysis. The method has been extended to cinnamyl alcohol, 1, 2-methyl-2-propen-1-01, 7, and 3-buten-2-01, 11, and to heterocyclic aldehydes.
