摘要

S-Aryl thiol esters RC (O) SAr and ArS2-ions are the end products resulting from the reactions between bis (2-nitrophenyl) disulfide Ar2S2 and thiocarboxylate ions RC (O) S-(R= Me, Ph) at 20° C. The apparent SNAr process in fact occurs in two steps as shown by UV-vis absorption spectrophotometry coupled with voltammetry:(i) formation of diacyl disulfides [RC (O)] 2S2 and ArS-ions by redox exchange;(ii) subsequent nucleophilic substitution of 2- ...
