Ion/molecule reactions in allene. III. Reactions of the parent ion with neutral alkanes

Abstract

Ion/molecule reactions between the ion C3H4+• ion, from allene and neutral alkanes were investigated by mass spectrometry. There are four H•/CH3•/H−/H2− transfer reactions and relative rate constants were calculated. The overall rates increased in the order CH4 < C2H6 < C3H8 < i-C4H10 < n-C4H10. There is also a stabilization process by alkanes of CeH8+• ion species, but its importance is lower than the above transfer processes.
