Abstract

The title reactions have been investigated in a static system. The addition of acetylene to cyclopentadiene (CPD) results in formation of norbornadiene (BCH), cycloheptatriene (CHT), and toluene (T), while BCH decomposition produces CPD, C~2~H~2~, CHT, and T. Kinetic studies, comprising both product–time evolution and initial pressure variation, support a mechanism

These reactions are almost certainly homogeneous and molecular in nature. Least mean square analysis of the data yield for temperatures of 525–656°K, log k~−1~ (1./mole·s)=7.51±0.05− (24.19±0.15 kcal/mole)/RT ln 10, and for temperatures of 584–630°K,

## Abstract The addition of ethene to cyclohexa‐1,3‐diene has been studied between 466 and 591 K at pressures ranging from 27 to 119 torr for ethene and 10 to 74 torr for cyclohexa‐1,3‐diene. The reaction is of the “Diels–Alder” type and leads to the formation of bicyclo[2.2.2]oct‐2‐ene. It is homo
