Palladium-catalyzed alkenation of thiophenes and furans by regioselective C-H bond functionalization
A palladium-catalyzed direct alkenation of thiophenes and furans has been developed in the presence of AgOAc and pyridine. A variety of olefinic substrates such as acrylates, acrylamides, and acrylonitrile can perform the direct oxidative coupling reactio
