Dechlorination of Substituted Trichloromethanes by an Iron(ii) Porphyrin
نویسندگان
چکیده
Iron(II) porphyrins complex with many organochlorine compounds and oxidize by dechlorinating them. For a series of trichloromethyl derivatives, CCl3R (R 5 NO2, CHCl2, CN, Cl, COO, CH3, H, C(O)NH2, and CH2OH), heme oxidation occurred in two consecutive steps: heme-CCl3R complexation, and (usually slower) inner-sphere electron transfer. Stability of the intermediate CCl2R radical, which is strongly correlated with the ability of the R group to delocalize electron density, governed the overall electron transfer rate. Keywords—Trichloromethanes Inner-sphere electron transfer Group electronegativity

Role of metalloporphyrin core metals in the mediated reductive dechlorination of tetrachloroethylene.
A promising approach to abiotically dechlorinate a variety of chlorinated organic contaminants under reducing conditions is to utilize porphyrins or other tetrapyrrole macrocycles as electron transfer mediators/shuttles for catalyzing their reduction. In this study, various experimental approaches were used to elucidate the role of porphyrin core metals in the reductive dechlorination of tetrac...

Reductive dechlorination of carbon tetrachloride (CT) and 1,1,1-trichloroethane (1,1,1-TCA) by FeS with transition metals (Cu(II), Co(II), and Ni(II)) and hydrosulfide was characterized in this study. The batch kinetic experiments were conducted by spiking each stock solution of CT and 1,1,1-TCA into 33 g/L of FeS suspensions with and without transition metals at pH 7.5. No significant enhancem...
