We report here our observation that, using appropriate reaction conditions, CsOH·H2O-promoted coupling of aryl halides with thiols can be performed in moderate to good yields without a transition metal catalyst. Copyright

Simple reaction conditions and recyclable reagents are crucial for environmentally friendly industrial applications. An environment-friendly, recyclable and economic strategy was developed to synthesize diaryl chalcogenides by the CuCl2-catalyzed C S bondformation reaction via iodobenzenes and benzenethiols/1,2-diphenyldisulfanes using N,N'-dimethylethane-1,2-diamine (DMEDA) as ligand, base, and solvent. For these reactions, especially the reactions of diiodobenzenes and aminobenzenethiols/disulfanediyldianilines, a range of substrates are compatible and give the corresponding products in good to excellent yields. Both of the reagents in the catalytic system (CuCl2/DMEDA) are inexpensive, conveniently separable, and recyclable for more than five cycles.

Based on the experimental and DFT calculation results, here for the first time we built preferential adsorption sites for nitroarenes by modification of the supported Cu catalysts surface with 1,10-phenathroline (1,10-phen), by which the yield of aniline via reduction of nitroarene is enhanced three times. Moreover, a macromolecular layer was in-situ generated on supported Cu catalysts to form a stable macromolecule modified supported Cu catalyst, i.e., CuAlOx-M. By applying the CuAlOx-M, a wide variety of nitroarene substrates react smoothly to afford the desired products in up to > 99% yield with > 99% selectivity. The method tolerates a variety of functional groups, including halides, ketone, amide, and C = C bond moieties. The excellent catalytic performance of the CuAlOx-M can be attributed to that the 1,10-phen modification benefits the preferential adsorption of nitrobenzene and slightly weakens adsorption of aniline on the supported nano-Cu surface.

A flavin/I2 catalyzed aerobic oxidative C–H sulfenylation of anilines with thiols under mild reaction conditions is presented for the first time. This metal-free reaction provides an atom-economic pathway to prepare various aryl sulfides with outstanding functional group compatibility. Moreover, it consumes molecular oxygen as the only terminal oxidant and produces environmentally-friendly H2O as the only byproduct.
