Abstract
Trichloroethylene (TCE) is an environmental contaminant that is subject to reductive degradation in natural and engineered systems. The reaction pathway for cobalamin, a common catalyst for reductive dechlorination, is unknown and both an outer sphere and a non-outer-sphere mechanism have been proposed. To further explore the role of the intermediates in the catalytic cycle, the reduction of cis-1,2- dichlorovinyl(pyridine)cobaloxime (1) , a model complex for the proposed intermediate formed in the dechlorination of TCE by cobalamin, was studied. The reduction of 1 was performed by again applying well-characterized outer-sphere electron-transfer agents and cobalamin in the presence of H atom and proton donor species to identify the presence of chlorovinyl radicals and anions. This work provides a further understanding of the cobalamin reduction of TCE. This is an abstract of a paper presented at the 231st ACS National Meeting (Atlanta, GA 3/26-30/2006).
