文摘Fully palladium/copper catalytic oxidative cross-coupling of acrylates with α-methylstyrene was performed in a DMSO/AcOH(1:1) mixture at 60℃ in the air.This improves previous procedures which employed stoichiometric amounts of copper and oxygen.Thus various acrylates were effectively coupled to α-methylstyrene giving the expected compounds in moderate to good yields(44%-65%) as a mixture of E and Z isomers.
