Bifunctional oxonium ions - generated from tertiary aliphatic alcohols containing an additional hydroxy, methoxy or chloro group at the end of an alkyl side-chain - do not markedly exhibit fragmentations typical of ordinary oxonium ions, but show as the main reactions those caused by functional group interaction, through-space interaction being the dominant factor.The main primary fragmentation is loss of the additional functional group X as HX, followed by loss of the side-chain originally separating the two functional groups, leading to carbonyl cations.This typical reaction sequence is initiated by proton migration from the oxonium moiety to the additional functional group.The reaction behaviour of the bifunctional ions is discussed.The lowest homologues show specific deviations from the general fragmentation behaviour.
Bifunctional Even-electron Ions. V. Fragmentation Behaviour of Aliphatic Hydroxonium Ions Containing an Additional Cyano Group

The fragmentation behaviour of a series of bifunctional hydroxonium ions C2H5-C(=O(1+)H)-CH2)n-CN (n = 0-6), an, has been investigated by electron impact mass spectrometry.The type of interaction-induced reactions depend strongly on
