The electrolytic reductive dechlorination of 1,1-bis(p-chlorophenyl)-2,2,2-trichloroethane (DDT) in the ionic liquid (IL) 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF(4)]) in the presence of a cobalamin derivative afforded 1,1'-(ethylidene)bis(4-chlorobenzene)(DDO) and 1,1'-(ethenylidene)bis(4-chlorobenzene)(DDNU) with 1,1'-(2-chloroethylidene)bis(4-chlorobenzene)(DDMS); the enhanced reactivity, as well as the recyclability of the cobalamin derivative catalyst in IL, makes the present system more efficient for the development of "green" technologies.
在钴胺素衍生物存在下，1,1-双（对氯苯基）-2,2,2-三氯乙烷（滴滴涕，DDT）在离子液体1-丁基-3-甲基咪唑四氟硼酸盐（[bmim][BF₄]）中进行电解还原脱氯反应，生成1,1'-（亚乙基）双（4-氯苯）（滴滴滴，DDO）和1,1'-（亚乙烯基）双（4-氯苯）（滴滴萘，DDNU）以及1,1'-（2-氯亚乙基）双（4-氯苯）（甲氧滴滴涕，DDMS）；钴胺素衍生物催化剂在离子液体中的反应活性增强以及可循环使用性，使得本体系在“绿色”技术开发方面更高效。
