文摘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 ofα-oxyalkylated ketones with broad functionalities has been synthesized in moderate to good yields.A radical mechanism is suggested for the present protocol.
