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] ionic liquid 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 (monoterpenes)/aromatic phenols/β-naphthols/aromatic amines and indoles without using any catalyst. A broad range of functional groups were well tolerated in this reaction system.

A simple, efficient and environmentally friendly method for iron or boron-catalyzed C-H arylthiation of substituted phenols at room temperature has been developed, and the corresponding diaryl sulfides were prepared in good to excellent yields. The protocol uses readily available 1-(substituted phenylthio)pyrrolidine-2,5-diones as the arylthiation reagents and inexpensive and environmentally friendly FeCl3 or BF3·OEt 2 as the catalyst, moreover no ligands, additives or extrusion of air are required, and the reactions can be performed successfully at room temperature.

Direct sulfenylation and selenylation of phenols using a stoichiometric amount of FeCl3 under an oxygen atmosphere has been developed. The chalcogenated phenols were shown to be suitable for preparing S- and Se-containing compounds using the reaction of the remaining hydroxy group.
