Competing fragmentation processes of beta-substituted propanoate ions upon collision-induced dissociation

摘要

RationaleWhen subjected to collisional activation, gas-phase carboxylate ions typically undergo decarboxylation. However, alternative fragmentation processes dominate when the carboxylate group is located within certain structural motifs. In this work, the fragmentation processes of -substituted carboxylate ions are characterized to improve correlations between reactivity and structure.
