摘要

Abstract: Metastable C4H80+-ions obtained from butanoic acid and ethyl butanoate undergo considerable y-hydrogen exchange prior to losing ethylene, but little exchange prior to losing methyl. Therefore the two fragmentations are not directly competing, contrary to the general assumption that all reactions of an ion in the gas phase are competitive. It is concluded that metastable butanoic acid ions which lose methyl isomerize essentially ...
