The C3H6O•+ isomeric ions I, II, CH2:CHOMe•+(III), C2H5CHO•+, CH3CH:CHOH•+, CH3COCH3•+, and CH2:CH(OH)CH3•+ are stable, with lifetimes >10-5 sec, and can be identified from their collisional activation (CA) spectra. Aliphatic terminal epoxides give a mixture of ions I and III, suggesting that the rearrangements involved are stepwise, not concerted. The C3H6O•+ ions formed by the loss of CH2O from the 2-methyl- and 4-methyl-1,3-dioxolane mol. ions have structure I; in a similar manner, 1,4-dioxane yields the cyclic ion II. The results show that the size of the cyclic transition state in hydrogen rearrangements is sensitive to a number of competing factors.
