A photo-oxidative homo-coupling of thiol was promoted by BrCCl3 in THF. This catalyst- and steel-cost-free technique was used to synthesize disulfides less than moderate problems. The clean up reaction minimized the risk of contamination of the item.
Abstract
This paper reported a catalyst- and metal-free of charge approach to build disulfide bond with BrCCl3 beneath mild irradiation. This thoroughly clean and mild response promoted the oxidative coupling of thiols with extensive substrate scope, and is relevant to benzylic, aryl and aliphatic thiols, in particular cysteine spinoff. The disulfides were obtained in substantial yields up to 98 %, steering clear of the use of heating, sturdy oxidant, metal reagent or catalyst. This facile system will facilitate the synthesis of disulfide compounds.
