  acetonitrile as the “CN” source has been achieved under a Cu(cat.)/TEMPO system (TEMPO=2,2,6,6‐tetramethylpiperidine N‐oxide). The broad substrate scope includes a variety of electron‐rich and electron‐poor arylboronic acids, which react well to give the cyanated products in high to excellent yields. Mechanistic studies reveal that TEMPOCH2CN, generated in situ, is an active cyanating reagent, and shows high
