- The ability of some transition-metal cofactors to catalyze the reductive dehalogenation of chlorinated ethylenes and benzene was studied. The bacterial transition-metal coenzymes vitamin B sub(12) (cobalt), enzyme F sub(430) (nickel), and hematin (iron) catalyzed the reductive dechlorination of the test compounds. For the vitamin and the coenzyme, reductive dechlorination rates for various classes of perchlorinated compounds decreased in the order of: carbon tetrachloride super( >) tetrachloroethylene super( >) hexachlorobenzene. Within each class of compounds, dechlorination rates decreased with decreasing chlorine content.
