Mechanism of Cobalamin-Mediated Reductive Dehalogenation of Chloroethylenes

ACS Catalysis, Год журнала: 2017, Номер 7(8), С. 5294 - 5307

Reductive dehalogenation involving cobalamin has been proved to be a promising strategy for decontamination of the polluted environment. However, cob(I)alamin can act both as strong reductant and powerful nucleophile, thus, several competing pathways may involved. This work uses experimentally calibrated density functional theory on realistic model resolve controversies cobalamin-mediated reduction chloroethylenes by exploring mechanisms electron transfer, nucleophilic substitution, addition. The computational results provide molecular-level insight into reacting with cob(I)alamin: computed ratios inner-sphere outer-sphere perchloroethylene trichloroethylene are 17:1 3.5:1, respectively, in accord corresponding experimental >10:1 >2.3:1, while pathway other less-chlorinated ethylenes is hampered high barriers (>25 kcal/mol). Thus, new mechanistic picture obtained which highly chlorinated primarily react via an nucleophilic-substitution pathway, whereas mainly through nucleophilic-addition pathway. Especially, quantitative comparison standard potentials between formed chlorinated-cobalamin cob(II)alamin/cob(I)alamin couple used distinguish whether proceed or not, linear free-energy relationships have developed predict reductive reactivity within given mechanism. Finally, we propose dual-isotope analyses distinguishing various environmental mechanisms.
