Abstract

The reactivity toward EtOH of nine carbonyl oxides (ROO) obtained by the thermolysis of the corresponding diazo compounds (RN2) is studied by the chemiluminescence method. The reactivity is characterized by the ratio of constants k EtOH 33/k 31, where k EtOH 33and k 31are the rate constants of the reactions of ROO with EtOH and RN2, respectively. The negative slope of the Taft correlations (ρ < 0) indicates the electrophilic character of the reaction of ROO with EtOH. The substituents, electron density acceptors, increase the relative reactivity of the carbonyl oxides.
