本文研究了系列金属卟啉对苯基氯(phCH~2Cl)和CO~2电羧化反应的催化活性.用熔点,MS,IR,UV鉴别产物为苯乙酸卟脂,利用高效液相色谱(HPLC)定量分析了羧化产物,选出最佳电羧化电解电位为-1.6v(相对于饱和甘汞电极,vs.SCE,下同). 并对催化活性较高的钴卟啉系列配合物进行了深入研究. 探讨了金属卟啉具有催化活性的原因,认为能形成M(Ⅰ)中间体的金属卟啉配合物.具有较高的催化活性.

The electrocarboxylation of benzyl chloride with CO2 catalyzed by metalloporphyrins and the effects of different kinds of central metals and ligands on catalytic activities are reported. Metalloporphyrins whose central metal can form corresponding M (I) complex compounds such as CoTPP (Co tetraphenylporphyrine), FeTPP, possess higher activities of catalysis. Metalloporphyrins with water-sol. ligands such as (Co, Fe)TPPS, (Co, Fe)TTMAPPI are better catalysts. Electron-withdrawing groups on the rings of porphyrins cause the lowing of metalloporphyrins' catalytic activities.
