摘要：

The mechanism of substitution of the bromine atom in (Z)-alpha-bromo-beta-arylthiovinyl phenyl sulphones, PhSO2CBr=CHSAr, with arylthiolates, Ar'S- was studied. The same mixture of the four possible products, PhSO2C(SAr')=CHSAr (Ar, Ar' = P-TOl,P-ClC6H4), was formed in both cross-experiments (Ar not-equal Ar'). A mechanism involving 1,2-intramolecular migration of the arylthio group is suggested.
