Gas-phase isomerizations in ion-radicals C4H8˙+ and C6H12˙+

Abstract

Ions C₄H₈˙⁺ have been generated in the mass spectrometer by ionization of the butenes, methyl-cyclopropane, and cyclobutane, and by loss of H₂O from ionized n-butanol, HF from ionized n-butyl fluoride, H₂S from ionized n-butanethiol, and AcOH from ionized n-butyl acetate. Competing metastable transitions from the resulting C₄H₈˙⁺ ions indicate decomposition from common states in all cases. Similarly, metastable transitions from C₆H₁₂˙⁺ ions, generated from many different precursors, also indicate decomposition from common states.
