Li, Yiming; Xie, Weisi; Jiang, Xuefeng published an article in 2015, the title of the article was Mechanistic Study of a Photocatalyzed C-S Bond Formation Involving Alkyl/Aryl Thiosulfate.Safety of Benzyl(4-bromophenyl)sulfane And the article contains the following content:
This study presents thioether construction involving alkyl/aryl thiosulfates and diazonium salt catalyzed by visible-light-excited [Ru(bpy)3Cl2] at room temperature in 44-86 % yield. ESR studies found that thiosulfate radical formation was promoted by K2CO3. Conversely, radicals generated from BnSH or BnSSBn (Bn=benzyl) were clearly suppressed, demonstrating the special property of thiosulfate in this system. Transient absorption spectra confirmed the electron-transfer process between [Ru(bpy)3Cl2] and 4-MeO-Ph diazonium salt, which occurred with a rate constant of 1.69×109 m-1 s-1. The corresponding radical trapping product was confirmed by X-ray diffraction. The full reaction mechanism was determined together with emission quenching data. Furthermore, this system efficiently avoided the over-oxidation of sulfide caused by H2O in the photoexcited system containing Ru2+. Both aryl and heteroaryl diazonium salts with various electronic properties were investigated for synthetic compatibility. Both alkyl- and aryl-substituted thiosulfates could be used as substrates. Notably, pharmaceutical derivatives afforded late-stage sulfuration smoothly under mild conditions. The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).Safety of Benzyl(4-bromophenyl)sulfane
