  Gas-phase Unimolecular Reactivity of C3H7O+ Cations: a Combined Mass Spectrometric-Molecular Orbital Study

  摘要：

  The unimolecular dissociations of the two isomeric ions [CH3CH2CHOH](+) (1) and [CH3CH2OCH2](+) (2) were re-examined. Molecular orbital calculations conducted at the MP2/6-31G*//HF/6-31G*+ZPE level were used to characterize the corresponding potential energy profile, The experimental data were completed by a Fourier transform ion cyclotron resonance spectrometric investigation on the system [CH2H](+)+C2H4 and by a study of various metastable [C3H7O](+) ions, The isomerization pathway of lowest energy connecting 1 and 2 involves two ion-neutral complexes between protonated formaldehyde and ethene. The isomerization 1 reversible arrow 2 is typically a complex mediated reaction since the key step consists simply of the reorientation of the two partners [CH2OH](+) and C2H4 inside the ion-neutral cage. The model is demonstrated to account for the H-D exchange observed during the dissociation of variously deuterated species. (C) 1997 by John Wiley & Sons, Ltd.

  Unimolecular reactions of βdistonic ion

  摘要：

  AbstractThe β‐distonic ion \documentclass{article}\pagestyle{empty}\begin{document}$ ^ \cdot {\rm CH}_2 {\rm CH}_2 \mathop {\rm O}\limits^ + {\rm HCH}_2 {\rm CH}_2 {\rm CH}_3 $\end{document} has been shown previously to be an intermediate in the fragmentation of ionized ethyl propyl ether. The reactions of this ion (generated by fragmentation in the ion source of alkyl propyl ethers of glycol) were studied in this work. Labelling showed that this ion undergoes competing hydrogen transfers leading to a series of isomeric distonic ions. Each of them was submitted to an isotope effect.
