A mild protocol for the α-C-H cyanation of tertiary aliphatic, benzylic, and aniline-type substrates and complex substrates tolerates a broad range of fuctional groups, including various heterocycles and ketones, amides, olefins, and alkynes. The presented catalyst system especially tolerates functional groups that typically react with free radicals, suggesting an alternative reaction pathway.
