New compounds based on the association of polyoxometalates and cationic porphyrins or metalloporphyrins were prepared with the aim of obtaining new bi-functional catalysts. A combined study on the syntheses, characterization and catalytic activity of these compounds was performed. The new compounds have the general formula (porphyrin)xHy[XM12O40]·z solv, x = 0.75 or 1, X = P or Si and M = W or Mo. The
基于多金属氧酸盐和阳离子卟啉或金属卟啉的缔合,制备了新的化合物,目的是获得新的双功能催化剂。对这些化合物的合成,表征和催化活性进行了综合研究。新化合物的通式为(卟啉)x H y [XM 12 O 40 ]· z溶剂,x = 0.75或1,X = P或Si,M = W或Mo。所用的卟啉为5,10,15 ,20-四(4-吡啶基)卟啉,5,10,15,20-四(1-甲基-4-吡啶基)卟啉,5,10,15-三(2,6-二氯苯基)-20-(4 -吡啶基)卟啉和5,10,15-三(2,6-二氯苯基)-20-(1-甲基-4-吡啶基)卟啉,可以游离碱形式或与Mn络合III(一例为Zn II)。与金属的几个化合物取代的Keggin阴离子([PW 11 ÿ(H 2 O)O- 39 ] ñ -,Y =锰,铁,镍,锌)还制备。所有化合物均通过光谱和分析技术进行了表征。的氧化的顺式3-蒈烯过氧化氢由所述多金属氧酸盐/
