✦ Synopsis


Bornylene (3,7,

hept-2-ene) undergoes a retro-Diels-Alder reaction at elevated temperatures in the gas phase to yield ethylene and 1,5,5-trimethylcyclopentadiene. The product 1,5,5-trimethylcyclopentadiene is unstable and a methyl shift occurs, giving rise to an equilibrium mixture of four C8 hydrocarbons (4).

We have studied these reactions in stirred flow reactor systems which have
