Electrochemical Benzylic C–H Amination via N-Aminopyridinium

An electrochemical protocol for benzylic C(sp3)–H aminopyridylation via direct C–H/N–H cross-coupling of alkylarenes with N-aminopyridinium triflate has been developed. This method features excellent site-selectivity, broad substrate scope, redox reagent-free and facile scalability. The generated benzylaminopyridiniums can be readily converted to benzylamines via electroreductive N–N bond cleavage.
