Production of Protonated Methanol Ions Via Intermolecular Reactions within Van der Waals Clusters of Dime Dimethyl Ether. Revision

Abstract

We report in this communication the first observation of protonated methanol generated within singly charged ion clusters of dimethyl ether. By studying the variation of ion intensity as a function of cluster size, we note that the ion cluster with the empirical formula of (CH3OCH3)2(CH3OH2)(+) is exceptionally intense in the mass spectrum. This novel 'magic number' we feel is due to the enhanced stability of 2 dimethyl ether molecules bonding (via hydrogen bonds) directly to the two hydroxy hydrogens. The formations of this cluster ion is rationalized in terms of a mechanism employing a trimethyloxonium cation which undergoes an internal rearrangement followed by decomposition to form protonated methanol and ethylene.
