A copper-mediated direct cyanation of indoles with benzyl cyanide as the cyanideanion surrogate has been achieved. The cascade reaction furnished 3-cyanoindoles under mild reaction conditions in good to excellent yields with various functional groups tolerance.

Herein, we report the C–H cyanation of indoles via a palladium-catalyzed directed C–CN activation reaction using aryl nitrile as a cyano source. The employment of the phenoxy-oriented group is the key to the cleavage of the C–CN bond. This protocol features a broad substrate scope, good efficiency, and high regioselectivity. Furthermore, the practical application of this protocol was showcased in the
