摘要

ArSOzM+ CH3CH20P (0) H2-ArSSAr(1) allowing a sulfinate salt to react with ethyl hypophosphite in dimethyl sulfoxide (Me2SO) overnight gives the corresponding disulfide (see Table I). For example, sodium benzenesulfinate is converted into phenyl disulfide in 64% yield. The reaction seems to be limited to aromatic sulfmate salts since all attempts to reduce aliphatic sulfinates4 did not yield clean products. Purification by distillation or ...
