A novel difunctionalization reaction of vinylarenes with cyclic ethers has been developed by copper catalysis via direct activation of alpha-sp(3) C-H bonds of oxygen in the presence of 1-1.2 equiv of TBHP under mild aerobic conditions. The reaction shows excellent regioselectivities and good functional group tolerance to give the oxyalkylated products of vinylarenes.

A new visible-light-promoted oxidative coupling of vinylarenes with cyclic ethers has been developed using rose bengal as photocatalyst and tert-butyl hydrogenperoxide (TBHP) as oxidant under ambient air at room temperature. A library of α-oxyalkylated ketones with broad functionalities has been synthesized in moderate to good yields. A radical mechanism is suggested for the present protocol
