Diazonium salts, which were in situ generated from p-anisidine and tert-butyl nitrite, could be used as a novel radical promoter for the Csp3–H functionalization of acetonitrile. The cyanomethylation of alkenes could be performed without the use of transition-metal salts or photocatalyst and the functionalized oxindoles could be obtained with simple operation in moderate to good yields.
