A tolerant POM: The efficient and selective direct alkenylation of benzofurans is achieved by using palladium acetate combined with 11-molybdovanadophosphoric acid. The transformation is performed under an atmosphere of dioxygen. Functional groups such as ethoxy, cyano, chloro, bromo, and ester are tolerated under the reaction conditions, and N-acetylglycine (Ac-Gly-OH) appears to be an effective additive for this reaction. 1 atm=101.3 kPa.
