本文报道了Pd 、Ir 取代的十二钼磷酸四丁基铵盐 (α (n Bu4 N) 5[PMo11Pd(OH2 )O39]、α (n Bu4 N) 3[PMo11Ir(OH2 )O39])的制备方法。IR、UV及31P NMR证实产物仍保持Keggin结构 ,并有一个Mo 为Pd 、Ir 所取代。电化学上 ,Ir 取代化合物存在三个清晰的多酸骨架氧化 还原峰而Pd 取代化合物由于电极吸附作用使它的氧化 还原峰无法被观察到。在两个取代化合物的烯烃催化氧化中醇、酮为主要产物。 值得注意的是 ,Pd 取代化合物催化的反应中苯酚取代环己烯酮而成为主要产物
The preparation of Pd, Ir-substituted tetrabutylammonium dodecamethylammonium phosphate (α (n Bu4N) 5 [PMo11Pd (OH2) O39] and α (n Bu4N) 3 [PMo11Ir (OH2) O39] method. IR, UV and 31P NMR confirmed that the product still retains Keggin structure, and a Mo is Pd, Ir substitution. Electrochemically, there are three clear polyoxo-acid redox peaks for the Ir-substituted compound and the Pd-substituted compound can not be observed for its redox peaks due to electrode adsorption. Alcohols and ketones are the main products in the olefin catalytic oxidation of two substituted compounds. It is noteworthy that the substitution of phenol for cyclohexene and the phenol in the reaction catalyzed by Pd became the major product
