Abstract

The mass spectra of a series of 1, 3-dioxo1-2-ones were examined for evidence of oxirenes in the fragmentation process. The M+--CO2 (oxirene or isomers) fragment was observed in six of eight samples. Four major pathways explain the mass spectra: M+.-C02-CO, M+.- CzO3, M+.-C202R and M+.-CO-C02. Metastable peaks support this. Similar pathways on pyrolysis were sought and observed. At 800" C and pressure of 1.5-4 mm, 1, 3-dioxol-2- ...
