Electrochemical Benzylic C-H Amination via N -Aminopyridinium.

An electrochemical protocol for benzylic C(sp 3 )-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.
