Abstract

ylenecyclohexane (161, both of which were identified by comparison with authentic specimens. This result was encouraging from the point of view of ita synthetic potential, it also provides qualitative confirmation of the conclusions reached by the force-field calculations, viz., that the isomerization 3-4 does have a significant energy barrier. A quantitative estimate of the activation energy temp, OC
