摘要

Competitive oxidative chlorination of p-substituted triarylstibines 3 [(p-XC6H4) 3Sb; a: X= OMe, c: Cl, d: CO2Et, e: CF3, f: CN, g: NO2] by sulfuryl chloride was carried out against 3b (X= H) and the electronic effect of these substituents on the chlorination of 3 was compared with that of homologous triarylbismuthanes 1. The relative ratios 4/4b (Ar3SbCl2/Ph3SbCl2) decreased with increasing electron-withdrawing ability of the substituents (a: 53/47, c: 49/ ...
