The First Example of a Catalytic Wittig-Type Reaction. Tri-n-butylarsine-Catalyzed Olefination in the Presence of Triphenyl Phosphite

Article abstract of DOI:10.1021/jo00270a001

Tri-n-butylarsine-catalyzed olefination was achieved by the reaction of various aldehydes with methyl bromoacetate (or ω-bromoacetophenone) in the presence of triphenyl phosphite and potassium carbonate at room temperature in good yields with high E stereoselectivity.
