Direct coupling of benzene with olefin catalyzed by Pd(OAc)(2) combined with heteropolyoxometalate under dioxygen.
The oxidative coupling reaction of benzenes with alkenes was successfully achieved by the Pd(OAc)(2)/molybdovanadophosphoric acid (HPMoV)/O(2) system. For example, the reaction of benzene with ethyl acrylate by the above catalytic system in acetic acid afforded ethyl cinnamate as a major product in satisfactory yield.
