Comprehensive kinetic and mechanistic considerations for the gas-phase behaviour of pinane-type compounds

, p. 2310 - 2317 (2008/02/08)
The thermal behaviour of selected pinane-type compounds, α-pinene (1), β-pinene (2), pinane (3) and nopinone (4), has been investigated. The conversion of the bicyclic starting materials to their acyclic and monocyclic isomers as well as the consecutive reactions of the acyclic main isomerisation products are discussed. The conversion of 1-4 in a reaction network is presented and the experimental evidence for the formation of pyrolysis products by a biradical pathway is discussed. In addition to these results a kinetic model describing the isomerisation of the bicyclic compounds to their acyclic and monocyclic isomers is presented. A good correlation between kinetic simulations and experimental data is revealed. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

(E)-1-Bromo-1-(4-methoxyphenyl)-1-propene (1a) reacts stereospecifically with (Z)-2-butene and silver tetrafluoroborate by cycloaddition of the intermediate vinyl cation 2a to give cis-1-(4-methoxyphenyl)-2,3,4-trimethyl-1-cyclobutene (3); with (E)-2-butene, 3 and trans-1-(4-methoxyphenyl)-2,3,4-trimethyl-1-cyclobutene (4) are formed in a ratio of 1:4.These results are in accord with a synchronous cycloaddition of the vinyl cation 2a to (Z)- and (E)-2-butene.Cyclohexene derivatives 14a, 14b, and 14c are obtained predominantly by the reaction of 1a and AgBF4 or AgSbF6 with vinylcyclopropane (11), ethyl vinyl ether (12), and isobutene (13), respectively.
