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

Article abstract of DOI:10.1002/jms.1190300315

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.
