1,2-Alkylarylation of Activated Alkenes with Two C-H Bonds by Using Visible-Light Catalysis

A new visible-light promoted strategy for the difunctionalization of activated alkenes with two C-H bonds has been developed. In the presence of [Ru(bpy)(3)Cl-2], 4-MeOC6H4N2BF4, Na2CO3 and 36W compact fluorescent light, a variety of N-arylacrylamides underwent the 1,2-alkylarylation reaction with acetonitrile or acetone to give the corresponding functionalized oxindoles in moderate to good yields.
