Abstract
AbstractThe primary and subsequent fragmentations of the bifunctional oxonium ions \documentclass{article}\pagestyle{empty}\begin{document}${\rm R} \!-\! \mathop {\rm C}\limits^ + ({\rm OH})\! -\! ({\rm CH}_2)_n \! - \! {\rm COOCH}_3 $\end{document} (n = 0−5), a, are dominated by functional group interactions. Loss of CH3OH is the only appreciable primary fragmentation of the higher homoiogues, but for the lowest homologue (a0) this reaction is missing. Instead, CO loss is observed. The next homologue (a1) shov.s loss of CH2CO besides loss of CH3OH. The mode of the subsequent fragmentations is dependent on the chain length separating the functional group, and formation of cyclic ions is typical of the fragmentation behaviour of a2 and a3. Evidence for proton transfer from the carbonyl oxygen to the methoxy group of a protonated ester group is presented.
