Abstract
Rate constants have been measured for the reaction of p-nitrophenyl diphenylphosphinate with aryloxides in ethanol. The reactivity of the less basic phenoxide decreases in the order K +-18-crown ether-6 > K + > Na + > Li +, which leads a conclusion that alkali metal-bound aryloxides are less reactive than the dissociated ones in the present system.
