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

2′-Aminoacetophenones undergo a C(sp 3 )–H oxidation followed by intramolecular C–N bond formation by virtue of a simple electrochemical oxidation in the presence of n -Bu 4 NI, providing various isatins with moderate to good yields. The reaction intermediates were detected, and a radical-based pathway was proposed.
