Abstract

An efficient and selective C2 alkenylation of benzofurans was performed by using Pd(OAc)2 combined with a catalytic amount of 11-molybdovanadophosphoric acid (H4PMo11VO40) under an atmosphere of dioxygen. N-Acetylglycine (Ac-Gly-OH) was observed to be an effective additive for the olefination reaction.
