but two: The title reaction proceeds through the dual CHbondcleavage of both aniline and acetonitrile (see scheme). The reaction affords a variety of cyano‐bearing indolinones in excellent yield. Mechanistic studies demonstrate that this reaction involves a fast arylation of the olefin and a rate‐determining CH activation of the acetonitrile.

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
