## Abstract A kinetic study of the nucleophilic substitution reaction of Y‐substituted phenyl diphenylphosphinothioates **2 a**–**g** with alkali‐metal ethoxides (MOEt; M=Li, Na, K) in anhydrous ethanol at (25.0±0.1) °C is reported. Plots of pseudo‐first‐order rate constants (__k__~obsd~) versus [M
