Ground-state destabilization of amides enables an exceedingly mild method for the direct thioesterification and selenoesterification by selective N-C(O) bond cleavage in the absence of transition metals. Acyclic amides undergo N-C(O) to S/Se-C(O) interconversion to give the corresponding thioesters and selenoesters in excellent yields at room temperature via a tetrahedral intermediate pathway.
