    Kinetics of the thermal gas phase reactions of 1,2-epoxy-2-methylpropane (1971)

    Notes: The kinetics of the gas phase decomposition of 1,2-epoxy-2-methylpropane has been studied over the temperature range 377°-436°C at pressures between 5.3 and 61.6 torr. Isomerization reactions to give isobutyraldehyde, isopropenyl methyl ether, and 2-methyl-prop-2-en-l-ol account for over 95% of the epoxide decomposition. These isomerizations are homogeneous first-order, nonradical processes: \documentclass{article}\pagestyle{empty}\begin{document}$$\begin{array}{l} k({\rm isobutyraldehyde)} = {\rm 10}^{{\rm 13}{\rm .32} \pm {\rm 0}{\rm .18}} \exp (- 52720 \pm 570/1.987T)\sec ^{- 1} \\ {\rm}k({\rm isopropenyl methyl ether)} = {\rm 10}^{{\rm 13}{\rm .55} \pm {\rm 0}{\rm .47}} \exp (- 56140 \pm 1460/1.987T)\sec ^{- 1} \\ {\rm}k({\rm 2 - methyl - prop - 2 - en - l - ol)} = {\rm 10}^{{\rm 11}{\rm .53} \pm {\rm 0}{\rm .67}} \exp (- 49680 \pm 2080/1.987T)\sec ^{- 1} \\ \end{array}$$\end{document}

    Notes: The kinetics of the gas-phase decomposition of 1,2-epoxycyclohexane has been studied over the temperature range 680-740 K at pressures between 1.6 and 6 torr. Isomerization to cyclohexanone and 2-cyclohexen-1-ol accounts for ca. 97% of the primary reaction products and occurs by first-order, homogeneous, nonradical processes: \documentclass{article}\pagestyle{empty}\begin{document}$$ k_{cyclohexanone} /s^{ - 1} = 10^{14.58 \pm 0.35} \exp \left( { - 60,300 \pm 1,100/1.987T} \right) $$\end{document} \documentclass{article}\pagestyle{empty}\begin{document}$$ k_{cyclohexanone - 1 - o1} /s^{ - 1} = 10^{13.11 \pm .41} \exp \left( { - 55,800 \pm 1,300/1.987T} \right) $$\end{document}

    Kinetic isotope effects in the thermal gas phase reactions of 1, 2-epoxycyclohexane-3, 3, 6, 6-d4 (1974)

    Notes: First-order rate constants for formation of cyclohexanone and 2-cyclohexen-1-ol from 1,2-epoxycyclohexane and 1,2-epoxycyclohexane-3,3,6,6-d4 have been determined over the temperature range of 677-746°K. The observed kinetic isotope effects are used in an attempt to determine the mechanism for formation of products. A distinction between a biradical and a concerted mechanism for the alcohol formation could not be made. However, if a common biradical is the precursor of both cyclohexanone and 2-cyclohexenl-ol then the rate of ring closure of this biradical must be much faster than the rates of hydrogen transfer to give the ketone and the alcohol.
