本文用两种炎氮杂冠醚聚合物作三相催化剂，研究了其对α－对氯苄基－α－（１，２，４－***－１－基）频哪酮合成反应的催化性能，考察了催化剂用量，反应介质和反应时间等条件对产率的影响。结果表明，含叔氨结构的类氮杂冠醚聚合物（Ⅱ）在苯及苯－水溶剂中均有良好的活性和较好的重复催化性能，而含仲胺结构的相应聚合物（Ⅰ）活性较差。

Catalytic synthesis of α- p - chlorobenzyl - α- (1, 2, 4 - triazol - 1 - yl) pinacolone using analogs of polymeric azacrown ethers as triphase catalysts was investigated, and the influence of reaction condition on the product yield was also discussed. The results show that the analogs of polymeric azacrown ethers with N - alkyl group (II) exhi...
