Thermolysis of 4-Methyl-4-phenyl Malonyl Peroxide: A New Oxygen Dependent Chemiluminescent Reaction

摘要

Thermolysis of 4-methyl-4-phenyl malonyl peroxide in acetonitrile is accelerated by electron donors, such as perylene. When both the perylene and oxygen are present in solution the reaction gives acetophenone and a small amount of light. Investigation of the mechanism of light generation reveals that it involves formation and fragmentation of a tetraoxide. The chemically initiated electron-exchange luminescence mechanism (CIEEL) appears to be responsible for light generation. (Author)
