摘　　要：利用固体光气法合成了4-氯苯基异氰酸酯,再进一步与3-氨基-1,2,4-三氮唑发生亲核加成反应合成了1-(4-氯苯基)-3-(1H-1,2,4-三氮唑-3-基)脲,目标产物结构用IR、UV进行了表征。植物生长调节活性测试表明,1-(4-氯苯基)-3-(1H-1,2,4-三氮唑-3-基)脲浓度为10 mg·L-1时对单子叶植物玉米和双子叶植物黄豆的生长具有较好的生长调节活性。1-（4-chlorphenyl）-3-triyl urea was synthesized by addition reaction of 3-amino-1, 2, 4-triazole and aromatic isocyanate, which was produced by triphosgene with phenylamine, and was characterized by UV and IR. According to the tests of plant growth regulating activity, 1-（4-chlorphenyl）-3-triyl urea, on ten milligram of per liter had the better activity of plant growth regulator on the monocotyledon corn and the dicotyledon soybean.
