Interconversions of C5H10O+. ions with the oxygen on the first, second and third carbons: Approximately 60 communicating isomers

The structures of the C4H7O+ and C3H6O+. dissociation products from selected C5H10O+. isomers with the oxygen on the first, second and third carbons were determined. The first product is CH3C(OH)CH=CH2+ and the second is CH3C(OH+)CH2. and CH3.CHCHOH+ in various proportions. These results demonstrate that ions with the oxygen on the first and third carbons isomerize partially to isomers with the oxygen on the second carbon. This and C5H10O+. isomers expected to be accessible to each other suggest that there are traversable pathways between about 60 C5H10O+. isomers, demonstrating how extensive interconversions of aliphatic radical cations can be.
