Radical cyanomethylation/arylation of arylacrylamides to access oxindoles with acetonitrile as the radical precursor is described. This reaction involves dualC–H bond functionalization, including the sp3 C–H of acetonitrile and the sp2 C–H of the phenyl group. A variety of functional groups, such as methoxy, ethyloxy carbonyl, chloro, bromo, iodo, nitro, trifluoromethoxy and trifluoromethyl groups
