oxidative cyclization reactions of unprotected 2-alkynylanilines with Oxone are described. The influences of several parameters including the substrate features, oxidant, reaction conditions, and catalyst on the reaction outcome were explored. A plausible mechanism is provided for the unusual silver-catalyzed oxidative cyclization reactions of 2-alkynylanilines to anthranils.
