Gan, Haifeng published the artcileFe/S-Catalyzed Redox Condensation of o-Nitrophenols/thiophenols/anilines with Dibenzyl Disulfide: Access to 2-Arylbenzazoles, Quality Control of 2622-67-5, the publication is ChemistrySelect (2020), 5(2), 717-721, database is CAplus.
An Fe/S-catalyzed approach to 2-arylbenzazoles I (R1 = H, 4-CH3, 4-OCH3, 4-F, 4-Cl, 4-C(CH3)3; R2 = 5-CH3, 6-Br, 5-C(O)2CH3, etc.; X = O, NH, NCH3, NC6H5, NCH2C6H5, S) and 2-phenyloxazolo[4,5-c]pyridine from dibenzyl disulfides (R1C6H4CH2S)2 and o-nitrophenols 2-NO2R2C6H3OH/thiophenols R1C6H4CH2SH/anilines 2-NO2R2C6H3NHR3 (R3 = H, Me, Ph, Bn) in the presence of base NMP has been developed. The reactions proceeded in moderate to excellent yields with good functional tolerance and gram-scale application. Mechanistic research indicated that Fe/S clusters play an important role in the formation of products and DMSO is also important to oxidize benzyl mercaptans to give dibenzyl disulfides.
