Electrocatalytic C–H/N–H Coupling of 2′-Aminoacetophenones for the Synthesis of Isatins

2′-Aminoacetophenones undergo a C­(sp3)–H oxidation followed by intramolecular C–N bond formation by virtue of a simple electrochemical oxidation in the presence of n-Bu4NI, providing various isatins with moderate to good yields. The reaction intermediates were detected, and a radical-based pathway was proposed.
