摘要
以硅胶为基质用γ－ＧＯＰＳ偶联后，接枝邻位氨基吡啶，间位、对位酰氨基吡啶三种配体后，与ＦｅＣｌ３或ＳｎＣｌ４饱和溶液络合，合成固载化的Ｌｅｗｉｓ酸催化剂，并以此类催化剂进行缩醛缩酮及酯化反应，获得良好效果．且催化剂可重复使用多次不失效。
Silica gel was functionalized by first reacting with r GOPS, then with three complexing functional compounds 2 aminopyridin, nicotinamide and isonicotinamide respectively. FeCl 3 or SnCl 4 was impregnated on this functionalized silica and six different immobilized catalysts were obtained. Condensation reaction of ketone and aldehyde as well as esterification have been performed on these catalysts and excellent results were obtained.
