The acrylonitrile dimer ion: A study of its dissociation via self-catalysis, self-protonation and cyclization into the pyrimidine radical cation (2007)

Ervasti, H.K., Jobst, K.J., Burgers, P.C., Ruttink, P.J.A., Terlouw, J.K.

Large energy barriers prohibit the rearrangement of solitary acrylonitrile ions, CH₂=CHC≡N•+, into their more stable hydrogen-shift isomers CH₂=C=C=NH•+ or CH=CH–C=NH•+. This prompted...

Dissociation of protonated oxalic acid [HOOC-C(OH)2]+ into H30++CO+CO2: an experimental and CBS-QB3 computational study (2006)

Ervasti, H.K., Lee, R., Burgers, P.C., Ruttink, P.J.A., Terlouw, J.K.

The predominant dissociation process observed for metastable protonated oxalic acid ions HOOC-C(OH)2+ (generated by self-protonation) leads to H3O++CO+CO2. We have traced the mechanism of this...

The loss of NH2O• from the N-hydroxyacetamide radical cation CH3C(=O)NHOH•+: An ion-catalysed rearrangement (2006)

Jobst, K.J., Burgers, P.C., Ruttink, P.J.A., Terlouw, J.K.

A previous study [Ch. Lifshitz, P.J.A. Ruttink, G. Schaftenaar, J.K. Terlouw, Rapid Commun. Mass Spectrom. 1 (1987) 61] shows that metastable N-hydroxyacetamide ions CH3C(=O)NHOH+ (HA-1) do not...

Formaldehyde mediated proton-transport catalysis in the ketene-water radical cation CH2=C(=O)OH2•+ (2006)

Lee, R., Ruttink, P.J.A., Burgers, P.C., Terlouw, J.K.

Previous studies have shown that the solitary ketene-water ion CH2=C(=O)OH2+ (1) does not isomerize into CH2=C(OH)2+ (2), its more stable hydrogen shift isomer. Tandem mass spectrometry based...

The acid-catalyzed rearrangement CH3Oo --> oCH2OH and its involvement in the dissociation of the methanol dimer radical cation; A Quid pro Quo reaction (2005)

Burgers, P.C., Ruttink, P.J.A.

The barrier for the radical isomerization CH3Oo --> oCH2OH is calculated by CBS-QB3 to be 29.7 kcal mol-1 and lies higher (by 5.7 kcal mol-1) than the dissociation limit CH2O+Ho. Hence, CH3Oo does...

On the dissociation characteristics of H2OH ions and their participation in the H2-catalysed isomerisation of OH to HO (1987)
