Abstract

The kinetics of the thermal reactions of bicyclo[4.2.2]deca‐3,7‐diene (BDD) and endo‐ and exo‐5‐vinylbicyclo[2.2.2]oct‐2‐ene (endo‐ and exo‐VBO) have been studied in the gas phase. The temperature range was 459–526 K for BDD, 476–563 K for endo‐VBO, and 513–578 K for exo‐VBO. The initial pressures were varied from 2 to about 40 torr. These compounds isomerize to cis‐1,2,4a,5,8,8a‐hexahydronaphtalene (HHN) and into each other, and decompose to 1,3‐butadiene (BD) + cyclohexa‐1,3‐diene (CHD). The reactions are homogeneous and first order. Their rate constants (in s^−1^) are given by:

## Abstract The reaction of acetylene (A) with cyclohexa‐1,3‐diene (CHD) has been studied between 450 and 592 K. The pressures of A ranged from 25 to 112 torr and those of CHD from 8 to 62 torr. The reaction yields only ethene (E) and benzene (B) instead of bicyclo[2.2.2]octa‐2,5‐diene (BOD), the p
