摘要
合成了系列Ｄａｗｓｏｎ结构钨钒磷杂多化合物（Ｃｐｙｒ）７＋ｎＰ２Ｗ１８－ｎＶｎＯ６２（ｎ＝１～３），并用ＩＲ，ＮＭＲ等手段对其结构进行了表征．考察了这类杂多化合物对苯酚过氧化氢的羟化活性，探讨了反应机理．
A series of tungstovanadophosphoric acids were synthesized and characterized with the methods of IR and NMR. The influence of V content, temperature, and Phenol/H 2O 2 molar ratio on catalytic activity was examined. The results of phenol hydroxylation with H 2O 2 in the presence of these heteropolycompounds are reported. Finally the mechanism of the reaction is discussed.
