Abstract
The decomposition of dimethyldioxirane (1) in oxygen-free acetone solutions (46°C) is accompanied by chemiluminescence (CL) in the visible spectral region. The emitter of CL is triplet-excited methyl acetate (2 *(T)). For the decomposition of solutions of1 in acetone and deuterated dimethyldioxirane in acetone-D6 the decay of CL follows the first-order kinetics, and the kinetic isotope effect is observed. Two mechanisms of the formation of2 *(T) are discussed: (a) chain-radical process and (b) isomerization of1 to2.
