| 摘 要： | 以一系列醛(酮)和氨基硫脲为原料,浓盐酸作催化剂,在室温条件下进行反应,合成了6个缩氨基硫脲类化合物,产品经元素分析、IR及1H NMR表征确定为目标化合物。将盐酸催化条件下的反应(Method A)与不使用催化剂条件下进行的反应(Method B)进行比较,结果表明,浓盐酸催化下的反应能够在1 h内完成,产品产率提高10%以上,达到90%,所以浓盐酸是合成该类化合物的高效催化剂。

| Abstract: | Six thiosemicarbazone derivatives were synthesized at room temperature using benzaldehyde or acetophenone and thiosemicarbazide as materials.The structure of these compounds were characterized by elemental analysis,IR and 1H NMR.The reaction only needs 1 h to proceed catalyzed by concentrated hydrogen chloride,and the yield of the product reached 90%.Compared the results of method A(using concentrated hydrogen chloride as catalyst)with method B(catalysis-free),the catalysis can increase the yields of the pr... |
