通过2-氨基-5-三氟甲基-1,3,4-噻二唑与芳酰基异氰酸酯反应,合成了10种新的芳酰基脲.它们的结构经元素分析、红外光谱、核磁共振氢谱进行了表征.并用X射线单晶衍射法测定了化合物2j的晶体结构,结果表明,该化合物晶体属三斜晶系,空间群为P-1,a=0.54191(15)nm,b=0.7766(2)nm,c=1.7161(5)nm,α=98.668(5)°,β=95.103(5)°,γ=101.070(5)°,V=0.6955(3)nm3,Z=2,Dc=1.653g/cm3,F(000)=352,μ=0.289mm-1.初步的生测试验结果表明一些目标化合物具有良好的植物生长调节活性.
Ten novel aroylureas were synthesized by the reaction of 2-amino-5-trifluoromethyl-1,3,4-thiadiazole with aroyl isocyanates.Their structures were characterized by elemental analysis, IR, 1H NMR The crystal structure of compound 2j was determined by single crystal X-ray diffraction. The crystal structure of compound 2j is triclinic with a space group of P-1, a = 0.54191 (15) nm and b = 0.7766 (2) nm, c = 1.7161 (5) nm, α = 98.668 (5) °, β = 95.103 (5) °, γ = 101.070 (5) °, V = 0.6955 = 1.653g / cm3, F (000) = 352, μ = 0.289mm-1. The preliminary bioassay results showed that some of the target compounds had good plant growth regulating activity.
