An environmentally benign method for the synthesis of aryl sulfides in water under mild conditions has been realized, in which arenes are coupled with equal stoichiometry of allyl sulfides. This arylthiolation is enabled by the presence of the Lipshutz surfactant, TPGS-750-M, using water as the recyclable reaction medium.

A simple, efficient and green method for the direct thiolation of aromaticcompounds using commercially available sulfonyl chlorides as the sulfur source was developed under metal- and solvent-free conditions. The C–S bond was constructed via direct C–H functionalization of diverse aromaticcompounds under an oxygen atmosphere. In this process, various diaryl sulfides were synthesized in moderate to

Novel and direct nucleophilic sulfenylation and thiocyanation of phenol ethers and related compounds (1) with the hypervalent iodine reagent, phenyliodine(III) bis(trifluoroacetate) (PIFA) have been developed. The reaction proceeded smoothly in 1,1,1,3,3,3-hexafluoro-2-propanol ((CF3)(2)-CHOH), a poorly nucleophilic and polar solvent. Various unsymmetrical diaryl sulfides and aryl thiocyanates, which could be applicable to the synthesis of various types of sulfur-containing aromatic compounds, were prepared in good yields. These reactions could be performed under mild conditions without heating or the use of strong Lewis acid catalysts.
