AbstractA simple and efficient method for arylthiolation of arylamines has been developed. The protocol uses (arylthio)pyrrolidine‐2,5‐diones as the arylthiolating reagents, acetonitrile as the solvent, and no catalyst and additive are required, which avoids contamination from the transition metal catalysts in the target products. Therefore, the present method should provide a convenient, efficient and practical strategy for the synthesis of other aryl sulfides.magnified image

A convenient and novel approach has been developed for the synthesis of unsymmetrical diaryl sulfides by the reaction of sulfonyl hydrazides with phenols using a [Bmim][Br] ionicliquid through the formation of C–S bonds. The reaction has further been extended to indole, β-naphthol and aromatic amine moieties. This protocol offers a new, versatile and greener approach for thiolation of natural phenols
