Hauser and Bernstein [13] also used almost the same type of mechanism during the pyrolysis of pentachloroethane. A summary of these reactions with supporting references is given in Table-1 [6, 11- 13].

The reagents of hexachloroethane, pentachloroethane, tetrachloroethylene, trichloroethylene, and dichloroethylene were all HPLC grade and were purchased from the Sigma Company.
The results of this experiment clearly indicated that, apart from transformation to PCE via [beta] reductive elimination, HCA can also undergo hydrogenolysis to produce pentachloroethane (PCA) and tetrachloroethane (TeCA) and then trichloroethane (TCA) and dichloroethane (DCA).
