Abstract
Abstract: Disubstituted acetophenones, XC4H4COCH2Y, and benzophenones, XC4H4COC6H4Y, are used to measure the cleavage rate constants, kru, of a series of a- substituted acetophenone ketyls and ring-substituted benzophenone ketyls. The cleavage rate constants can be determined from the competitive rates of fragmentation, kW/krx, of a series of ketyls,[XC6H4COCH2Y]'-and [XC6H4COC6H4Y]:-, since the rate constants, krx, ...
