Abstract

The thermal decomposition of ethylallylether (EAE) has been studied in the gas phase over the temperature range of 560–648°K. Propylene and acetaldehyde are the only reaction products observed. The reaction is apparently homogeneous in nature and independent of the pressure of EAE and of added foreign gases. The experimetally determined first‐order rate constants, using the internal standard technique, fit the Arrhenius relationship log k(s^−1^) = 11.84 ± 0.29 − (43.57 ± 0.77 kcal/mole)/2.303__RT.__ Independently the same rate constants are obtained, based on the amounts of products formed. The observed activation parameters are in general agreement with expectations based on the concept of a 6‐center 1,5‐H‐shift retro‐“ene” reaction mechanism, and they agree with previous results obtained for the similar reactions involving alkylallylamines and olefins.

## 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
