• Mechanism of propene and water elimination from the oxonium ion CH₃CHO⁺CH₂CH₂CH₃

  The site-selectivity in the hydrogen transfer step(s) which result in propene and water loss from metastable oxonium ions generated as CH3CH=O+CH2CH2CH3 have been investigated by deuterium-labelling experiments. Propene elimination proceeds predominantly by transfer of a hydrogen atom from the initial propyl-substituent to oxygen. However, the site-selectivity for this process is inconsistent with beta-hydrogen transfer involving a four-centre transition state. The preference for apparent alpha- or gamma-hydrogen transfer is interpreted by a mechanism in which the initial propyl cation accessible by stretching the appropriate bond in CH3CH=O+CH2CH2CH3 isomerizes unidirectionally to an isopropyl cation, which then undergoes proton abstraction-from either methyl group CH3CH=O+CH2CH2CH3 --> CH3CH=O--- (CH2CH2CH3)-C-+ --> [CH3CH-O (CH)-C-+(CH3)(2)] --> [CH3CH=OH+ CH3CH=CH2]}. This mechanism involving ion-neutral complexes can be elaborated to accommodate the minor contribution of expulsion of propene containing hydrogen atoms originally located on the two-carbon chain. Water elimination resembles propene loss insofar as there is a strong preference for selecting the hydrogen atoms from the alpha- and gamma-positions of the initial propyl group. The bulk of water loss is explicable by an extension of the mechanism for propene loss, with the result that one hydrogen atom is eventually transferred to oxygen from each of the two methyl groups in the complex [CH3CH=O- (CH)-C-+(CH3)(2)]. This site-selectivity is strikingly different from that (almost random participation of the seven hydrogen atoms of the propyl substituent) encountered in the corresponding fragmentation of the lower homologue CH2O+CH2CH2CH(3). This contrast is explained in terms of the differences in the relative energetics and associated rates of the cation rearrangement and hydrogen transfer steps.

  AbstractThe reactions of the metastable oxonium ions CH3CH2CH2CH2+O = CH2 and CH3CH2CH2 = O+ CH3 are reported and discussed. Both these isomers of C5H11O+ expel predominantly CH2O (75–90% of the metastable ion current), a moderate amount of C3H6 (5–15%), a minor amount of CH3OH (2–8%) and a very small proportion of H2O (0.5–3%). All these processes give rise to Gaussian metastable peaks. The kinetic energy releases associated with fragmentation of these oxonium ions are similar, but slightly larger for dissociation of CH3CH2CH2CH = O+CH3. The behaviour of labelled analogues confirm that the reactions of CH3CH2CH2CH = O+CH3 are closely related, but subtly different. Elimination of CH2O and C3H6 is intelligible by means of mechanisms involving CH3CH+CH2CH2OCH3. This open‐chain cation is accessible to CH3CH2CH2 +O = CH2 by a 1,5‐H shift and to CH3CH2CH2‐CH = O+CH3 by two consecutive 1,2‐H shifts (or, possibly, a direct 1,3‐H shift). The rates of these 1,2‐, 1,3‐ and 1,5‐H shifts are compared with one another and also with the rates of CH2O and C3H6 loss from each of the two oxonium ions. The 1,5‐H shift that converts CH3CH+CH2CH2OCH3 formed from CH3CH2CH2CH = O+ CH3 into CH3CH2CH2+O = CH2 prior to CH2O elimination is essentially unidirectional. In contrast, the corresponding step converting C5H11O+ ions generated as CH3CH2CH2CH2+O = CH2 into CH3CH+ CH2CH2OCH3 competes effectively with expulsion of CH2O and C3H6. The implications of the latter finding for the degree of concert in the hydrogen transfer and carbon‐carbon bond fission steps in alkene losses from oxonium ions via routes that are formally isoelectronic with the retro ‘ene’ pericyclic process are emphasized.
