摘　　要：以不同芳香胺为原料,1,2-二氯乙烷作溶剂,首先,采用固体光气法合成了不同的芳香异氰酸酯,由二氰二胺和叠氮化钠合成了5-氨基四唑;然后,芳香异氰酸酯和5-氨基四唑反应生成不同的芳香四唑脲。分别对四唑脲进行了物理常数、UV、IR的测定,对其波谱进行系统的分析和研究,来确定目标化合物。研究了四唑脲对丝瓜生长的调节活性,结果发现,目标化合物均有较好的植物生长调节活性。With different aromatic amines as raw material,1,2-dichloroethane as solvent,different aromatic isocyanates were synthesized by solid phosgene method.5-Amino tetrazole was synthesized from dicyanodiamide and sodium azide.Then romatic isocyanate and 5-amino tetrazole reacted to form different aromatic tetrazole ureas.The physical constants,UV and IR of tetrazole ureas were determined respectively,and tetrazole ureas were identified as target compounds by systematic spectral analysis and study.Through determing the plant growth activity of tetrazole ureas on towel gourd,it is found that these compounds have good activity as plant growth regulator.
