✦ Synopsis
De Mare et al. [13 studied the thermal Diels-Alder dimerization of cyclohexa-1,3-diene (CHD) to endo-dicyclohexadiene and exo-dicyclohexadiene (N and X, respectively) in a static Pyrex system. The temperature ranged from 471 to 639 K and the pressure was varied from 25 tp 630 torr. The formations of N and X are second order and 67, 1397 (1971).

Selectivity-reactivity correlations are shown to support a biradical pathway for the gas phase thermal Diels-Alder reactions of cyclohexa-1,3-diene with substituted ethenes except for those involving a carbonyl group. \* All cycloadducts are considered as endo or ex0 according to the orientation of
## Abstract The thermal reactions of 1,3‐butadiene (BD) with cyclohexa‐1,3‐diene (CHD) have been studied in a static system between 437 and 526 K. The pressures of BD and CHD were varied from 61 to 397 torr and from 50 to 93 torr, respectively. The percentages of consumed BD and CHD were always kep
## Abstract The Diels–Alder addition of acrolein to cyclohexa‐1,3‐diene has been studied between 486 and 571°K at pressures ranging from 55 to 240 torr. The products are endo‐ and exo‐5‐formylbicyclo[2.2.2]oct‐2‐ene (endo‐ and exo‐FBO), and their formations are second order. The rate constants (in
## 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
