Metalated nitriles and enolates rapidly and efficiently abstract chlorine from 2-chloro-2-fluoro-2-phenylacetonitrile to afford a diverse range of chloronitriles and chloroesters. The method provides the first general anionic chlorination of alkylnitriles, tolerates numerous functional groups, and addresses the challenge of synthesizing alpha-chloronitriles under mild conditions.

important heterocyclic motifs of pyrrolidines and piperidines within a uniform reaction protocol. The mechanism of this unprecedented C–H amination strategy involves anodic C–H activation to generate a benzylic cation, which is efficiently trapped by a nitrogen nucleophile. The applicability of the process is demonstrated for 40 examples comprising both 5- and 6-membered ring formations.
