pd(ii)/hpmov-catalyzed direct oxidative coupling reaction of benzenes with olefins

The direct aerobic coupling reaction of arenes with olefins was successfully achieved by the use of Pd(OAc)2/molybdovanadophosphoric acid (HPMoV) as a key catalyst under 1 atm of dioxygen. This catalytic system could be extended to the coupling reaction of various substituted benzenes with olefins such as acrylates, aclrolein, and ethylene through the direct aromatic C-H bond activation.
