✦ Synopsis

The gas-phase thermal isomerization of hexachlorocyclopropane to hexachloropropene at 208-283OC is first order and unaffected by changes in the surface-to-volume ratio or by the addition of iodine, tetrachloroethylene, and oxygen. The first-order rate constants fit the Arrhenius equation log k(s-') = (15.74 f 0.22) -(45,660 f 526)/4.576T

The reaction was interpreted as an unimolecular process taking place with chlorine atom migration. A comparison of the reactivities of several chlorocyclopropanes is made.

The gas phase thermal isomerization of 4-acetyl-5-methyl-isoxazole affords 3-cyano-2,4-pentanedione as the only product in good agreement with previous proposed isomerization mechanism for isoxazoles. On the other hand, kinetic parameters and MO theoretical calculations do not agree with those previ

The gas-phase thermal isomerization of N-propylidenecyclopropylamine has been studied in the temperature range of 573" to 635°K. The reaction is homogeneous and kinetically first order and yields 5-ethyl-1-pyrroline as the sole product. The rate constants are independent of pressure in the range of
