Abstract
The addition of propene to cyclohexa‐1,3‐diene has been studied between 512 and 638°K at pressures between 70 and 640 torr. The products are endo‐ and exo‐5‐methylbicyclo [2.2.2] oct‐2‐ene, and their formations are second order. The rate constants (in 1./mole‐sec) are given by
The results are discussed in terms of a biradical mechanism.

## 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
## 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
