Kinetic study of a retro Diels–Alder reaction in a single‐pulse shock tube: Decyclization of 1‐methylcyclohex‐1‐ene
TLDR
In this article, the gas-phase decomposition of 1-methylcyclohex-1-ene has been studied over the temperature range of 1000°-1180° K in a single-pulse shock tube using a comparative-rate technique.Abstract:
The kinetics of the gas-phase decomposition of 1-methylcyclohex-1-ene has been studied over the temperature range of 1000°–1180° K in a single-pulse shock tube using a comparative-rate technique. The retro Diels-Alder reaction to ethylene and isoprene accounts for the bulk of the products with a rate constant given byread more

The Retro–Diels–Alder Reaction Part I. C ? C Dienophiles
TL;DR: A comprehensive review of the literature on retro Diels-Alder reactions can be found in this article, with a focus on expelling C-C dienophiles, i.e. those reactions that generate a new carbon-carbon double or triple bond in the dienophile.

Chapter 16.4 - Chemical and Combustion Kinetics: 16.4 Single-Pulse Shock Tube
Wing Tsang,Assa Lifshitz +1 more
TL;DR: In this paper, a detailed discussion of how experiments are carried out and the type of kinetic problems that are accessible through single-pulse shock tube studies is presented, where the emphasis is on the understanding of the mechanisms and rate constants for the decomposition reactions of a particular molecule.

Isomerization of cis-1,2-Dimethylcyclohexane in Single-Pulse Shock Tube Experiments
TL;DR: The presence of the isomeric octenes suggests that internal disproportionation is an important component of the wasomerization process, and the rate constants are over an order of magnitude smaller than the equivalent noncyclic hydrocarbon system.

Concerted cycloaddition reactions: a study using the parabolic model and quantum chemical modeling
TL;DR: In this paper, the activation energies of cycloaddition reactions were investigated using the intersecting parabolas (M3IP) method and quantum chemical calculations, including the enthalpy of reaction, substituents and the molecular structure of reactants.

Studies with a Single‐Pulse Shock Tube. I. The Cis—Trans Isomerization of Butene‐2
TL;DR: In this paper, the cis-trans isomerization of butene was investigated behind reflected shocks in a single-pulse shock tube of a novel design, and an activation energy of 65, rather than 62.8 kcal/mole, was obtained when a straight line was drawn between the high and low temperature data.
