Visible-light-mediated oxidative arylation of vinylarenes under aerobic conditions†
Abstract
A mild and efficient method for the photocatalytic oxidative arylation of vinylarenes to generate 1,2-diarylated ethanones has been developed. The reaction was catalyzed by Ru(bpy)3Cl2 at room temperature under aerobic conditions. This protocol realizes a controllable, regioselective 1,2-difunctionalization of carbon–carbon double bonds.
