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.

In this study, an FeCl3·6H2O/cationic 2,2â²-bipyridyl system was employed as a catalyst in the coupling of aryl iodides with thiols to form an arylâsulfur bond in refluxed water under aerobic conditions. The residual aqueous solution after extraction could be reused for several cycles without a significant decrease in activity.
