A metal-free visible-light-promoted oxidative coupling between thiols and arylhydrazines has been developed to afford diaryl sulfides using a catalytic amount of rose bengal as photocatalyst under aerobic conditions. A library of unsymmetrical diaryl sulfides with broad functionalities was synthesized in good yields at room temperature. The present methodology is also applicable to benzo[ d]thiazole-2-thiols

difficult reactions and the synthesis of complexed molecules such as benzothiazole-sulfide aryls. In this work, CuI was successfully immobilized on the surface of magnetic Fe3O4 nanoparticles modified with aniline and 4-aminobenzoic acid [Fe3O4@ABA-Aniline-CuI nanocomposite] and its catalytic activity was investigated in the preparation of a broad range of benzothiazole-sulfide aryls and heteroaryls through

graphicA new synthesis of thioethers is described. The reaction of boronic acids with aryl, heteroaryl, and alkyl N-thloimides in the presence of catalytic quantities of a Cu(l) carboxylate affords good to excellent yields of thioethers. This reaction takes place in the absence of a base under mild conditions (THF, 45-50 degreesC, 2.5-12 h) and represents an interesting complement to known methods for thioether synthesis.
