✦ Synopsis

An analysis of the thermochemistry of the kinetic parameters of the elementary reactions involved in the pyrolysis of pentachloroethane has resolved several disputed, unclarified, or inconsistent aspects of the reaction mechanism. The resulting mechanisms for the inhibited and uninhibited pyrolysis account for all reported experimental findings. On the basis of this interpretation, first experimentally based values have been derived for the following: DH0(CC13-CHC12) = 79.0 f 1.0 kcal/mol, AH)'(cHCIz) = 25.7 f 1.0 kcal/mol, and El = 59.7 f 1.0 kcal/mol (CZHC15 HC1+ CzC14).

It is shown that kinetic data on the polymerization of acetylene to vinyl acetylene and benzene can be reconciled with the formation of a 1,4 biradical which can isomerize by a 1-3, H-atom shift to the molecular product. Since the biradicals have a negligibly small life-time in the system the overal
