Theoretical investigation of the mechanism for the reductive dehalogenation of methyl halides mediated by the CoI-based compounds cobalamin and cobaloxime

Journal of Molecular Modeling, 24(11).

By: J. Terán*, C. Zambrano*, J. Mora*, L. Rincón* & F. Torres*

Contributors: J. Terán*, C. Zambrano*, J. Mora*, L. Rincón* & F. Torres*

author keywords: Organohalides; DFT; Cobalt complexes; Reductive dehalogenation
TL;DR: A comparison of all the determined parameters showed that the reaction in the DMB–CoICbx system resembles the process that occurs in the larger CoICbl, suggesting that the former system could be a reliable model for the study of reductive dehalogenation mediated by vitamin B12, which is key to the anaerobic microbiological treatment of halocarbon contaminants.
