Ozonolysis of Diphenylvinylene Carbonate. The Synthesis and Thermolysis of Dibenzoylmono-peroxycarbonate.
Abstract
Dibenzoylmonoperoxycarbonate (I) was prepared by the reaction of diphenylvinylene carbonate with ozone. The thermolysis of I in benzene gives products typical of the formation of benzoyloxy radicals. The reaction rate was investigated at different temperatures and the activation parameters were determined (delta H = 27.8 + or - 1.2 kcal/mol, delta S =6.1 + or - 3.5 eu). The thermolysis of I in the presence of the stable free radical galvinoyl was investigated also. These experiments revealed that the fraction of radical escape from the solvent cage is 60 + or - 5%.
