A PhI(OAc)2-promoted reaction for the synthesis of 2-(aryl/alkylthio)phenol derivatives has been developed, which was realized via dehydrogenation oxidation between ortho-C(sp2)—H of phenols and S—H of thiophenols for direct formation of C—S bonds. Particularly, this method was also successfully applied for the efficient construction of tricyclic 10H-phenothiazines using 2-aminothiophenols as the substrates. All the newly synthesized products were identified by means of 1H NMR, 13C NMR, IR and HRMS. Besides, 2-((4-bromophenyl)thio)benzene-1,4-diol (3i) was further confirmed by X-ray single crystal diffraction analysis. The method has the advantages of simple and easily available starting materials, mild reaction conditions, simple operation, as well as high atom economy.

Key words: 2-(aryl/alkylthio)phenols, 10H-phenothiazines, dehydrogenation oxidation, C—S bond formation
