The gas phase pyrolyses of exo-2-norbornyl chloride and cyclopentyl chloride were studied in the temperature range 570–670 K. The results obtained show that these compounds behave as typical secondary halides insofar as the kinetics of their hydrogen chloride elimination reactions are concerned. Labelling experiments showed that in the formation of both norbornene and cyclopentene, a cis-1,2 elimination with a deuterium isotope effect of ∼3 was involved. Nortricyclene also was produced from exo-2-norbornyl chloride, via a trans 1,3 elimination; this process is analogous to a fragmentation of the ionized molecule. No gas phase Wagner–Meerwein rearrangement was involved in the formation of either norbornene or nortricyclene.

The kinetics of the thermal decomposition of ethyl, isopropyl, and t-butyl cyanides into HCN and the corresponding defines have been studied in a seasoned silica vessel in a flow system in the absence and presence of toluene as inhibitor. The reactions are homogeneous and the unimolecular rate constants are expressible by the following Arrhenius equations:[Formula: see text]
