Abstract
Acid dissociation constants of 10 substituted phenols have been measur ed by a kinetic method together with second-order rate constants for t he reactions of aryl benzoates (X-C6H4CO-OC6H4-Y) with Z-substituted p henoxide (Z-C6H4O-) and EtO(-) in absolute ethanol at 25.0+/-0.1 degre es C. The kinetic results support a stepwise mechanism for the present acyl-transfer reaction. (C) 1997 Elsevier Science Ltd.
