Electrochemical Selective Benzylic C(sp3)–H Amination of Amino Group‐Substituted Alkylarenes with Benzimidazoles

Abstract An electrochemical benzylic C(sp 3 )–H amination reaction of amino group‐substituted alkylarenes with benzimidazoles was developed. The reaction showed good selectivity, and C−H cleavage occurred selectively at the benzylic position other than the α ‐position of the amino group. Atom‐ and step‐economic, catalyst‐free, external oxidant‐free, H 2 as the only and clean byproduct are the additional characteristics of this electrochemical reaction.
