single‐step synthesis of aryl thiols from arylhalides has been developed employing copper(II) catalyst and 1,2‐ethanedithiol. The key features are use of readily available reagents, a simple operation, and relatively mild reaction conditions. This new protocol shows a broad substrate scope with excellent functional group compatibility. A variety of aryl thiols are directly prepared from arylhalides in high
nanoparticles efficiently catalyzed the C–S cross coupling of aryl and alkyl thiols with aryl halides in the absence of ligands on water under mild conditions. A wide range of diaryl sulfides and aryl alkyl sulfides are synthesized in good to excellent yields utilizing this protocol. This procedure is particularly noteworthy given its mild conditions, avoiding the undesired formation of disulfides through
A flavin/I2 catalyzedaerobic oxidative CH 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
首次提出在温和的反应条件下,黄素/ I 2催化苯胺与硫醇的好氧氧化C H亚磺酰化反应。这种无金属的反应为制备具有出色官能团相容性的各种芳基硫化物提供了一条原子经济途径。此外,它消耗分子氧作为唯一的终端氧化剂,并产生环保的H 2 O作为唯一的副产物。

thiolation of unprotected anilines with thiols for the synthesis of sulfide anilines has been described. The combinational use of I2 and DMSO played an important role to realize this kind of transformation without the aid of a metal catalyst and strong oxidants. The reaction selectivity was well controlled to provide mono-, bis-, and trisubstituted diaryl sulfide derivatives. More importantly, iodination
Phenyl-substituted perfluoroalkanesulfonanilides in which the phenyl rings are linked by sulfur, sulfinyl or sulfonyl and salts thereof in which the rings and the perfluoroalkylsulfonamido nitrogen are optionally substituted. The compounds are active herbicides and some are anti-inflammatory agents and analgesic agents.
