In 2022,Iali, Wissam; Suleiman, Rami K.; El Ali, Bassam published an article in Applied Organometallic Chemistry. The title of the article was 《Highly efficient NHC-iridium(I) catalyzed disulfide bond forming reaction》.Recommanded Product: 1,2-Diphenyldisulfane The author mentioned the following in the article:
The N-heterocyclic carbene (NHC) iridium(I) complex [IrCl (COD)(IMes)] [IMes = 1,3-bis(2,4,6-trimethylphenyl) imidazole-2-ylidene] showed an excellent catalytic activity in the reactions of the aerobic oxidative coupling of thiols into disulfides RSSR1 [R = R1 = nPr, Ph, (CH2)2OH, etc.]. The use of oxygen of air as a green oxidant allowed the thiols to be quant. converted into the corresponding disulfides under mild conditions and in a short reaction time. The replacement of chloride ligand on the iridium by the strong-donating thiolate ligand yielded an electron-rich and sensitive-to-oxygen active species [Ir(S-R)(COD)(IMes)] at room light and subsequently promoted the catalytic oxidative coupling reactions. This active species was successfully isolated and characterized by X-ray diffraction and found also to be essential in revealed a plausible mechanism for this Ir-catalyzed transformation. The D. Functional Theory (DFT)-calculated free energy profile of the proposed mechanism of catalyst system could reasonably account for the key role of air in pursuing the catalytic reaction. The results came from multiple reactions, including the reaction of 1,2-Diphenyldisulfane(cas: 882-33-7Recommanded Product: 1,2-Diphenyldisulfane)
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers. Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. Recommanded Product: 1,2-Diphenyldisulfane
