Abstract: Carbon kinetic isotope effects on the hydrolysis of aryl carbonates in 1: l (v/v) dioxane-water at 25 OC at various pHs were used to calculate isotope effects on the reactions with hydroxide ion and with water. For diphenyl carbonate kOH12/kOH13= 1.0482 and kwI2/kwI3= 1.0509. For bis@-methoxypheny1) carbonate kOH12/&OH13= 1.0493 and kwl2/kwl3= 1.0518. For bis (p-nitropheny1) carbonate ko~'*/Ko~'~= 1.0476. The small ...
