2-(Alkylamino)benzonitriles were synthesized via a rhodium-catalyzed cyanation on the aryl C–H bond and subsequent denitrosation of N-nitrosoarylamines using a removable nitroso as the directing group, in which N-cyano-N-phenyl-p-methylbenzenesulfonamide (NCTS) was used as the “CN” source. Various substituents on the aryl ring and amino group of N-nitrosoarylamines tolerated the reaction, and the corresponding

An efficient aminocyanation by the direct addition of aryl cyanamides to arynes is described, enabling incorporation of highly useful amino and cyano groups synchronously via cleavage of inert N-CN bonds, affording synthetically useful 1,2-bifunctional aminobenzonitriles. The postsynthetic functionalization of the aminocyanation products allows diverse formation of synthetically important derivatives such as drug molecule Ponstan and fused heterocycles.
