MASS SPECTROMETRY OF CYCLIC ORGANIC PEROXIDES

The mass spectra of some cyclic peroxides are reported; in each case the mode of formation of the major fragment ions are tentatively described. It is concluded that, even in the absence of a molecular ion, peroxides of this type can be identified by mass spectrometry. The heterocycle comprising the four oxygen atoms appears to be less stable than the phenyl ring but more stable than the cyclohexyl ring toward electron impact. © 1968, American Chemical Society.
