摘要： 研究了碘化四-(4-三甲胺基苯基)卟啉钴和VB12催化CO2与卤代丁烷的电合成。该反应在-1.5V(vs.SCE)即可发生,VB12催化产物为预期的戊酸丁酯,而CoTPP催化产物为CO2直接还原的草酸二丁酯,并未发现CO2与卤代丁烷的反应产物。初步探讨了产生不同产物的原因。

Abstract: The catalyzation of cobalt etrakis(4-trimethylaniline) porphyrin and vitamine B12for electrocarboxylation of halobutane with CO2 are studied.The electrocarboxylation in the presence of catalysts can occur at a more positive potential(-1.6Vvs.SCE) than that without catalysts, The products of electrolysis are butyl oxalate(calalyzed by CoTTMAP) and butyl valerate(catalyzed by VB12).The reason of producing different results of electrocarboxylation was researched by means of spectroelectrochemistry.

Key words: Metalloporphyrin, Electrocarboxylation, Vitarnine B12
