An efficient and chemodivergent palladium-catalyzed thiolation (C–S) and imidation (C–N) of directing group-assisted C–H bonds have been accomplished employing N-(arylthio)imides in combination with either Brønsted acid or Lewis acid, respectively. Notable features of the developed methodologies include excellent diversity, high functional group tolerance, wide substrate scope, and use of a single N–S reagent. Importantly, the developed hypothesis was also successfully extended to the amidation of C–H bonds. A plausible mechanistic pathway was proposed based on the preliminary mechanistic study.
