为了寻找新的高活性农药, 利用工业易得的三氟羧草醚及其中间体为起始原料, 设计合成了9个未见报道的N-取代苯甲酰基-N'-取代芳基硫脲化合物, 结构经IR, ~1H NMR, 元素分析确认. X射线衍射测定了化合物4b的晶体结构, 结果表明: 其分子属于三斜晶系, 空间群P-1, a=0.51588(19) nm, b=1.0766(4) nm, c=2.0596(8) nm, α=81.113(6)°, β=89.702(6)°, γ=78.131(6)°, V=1.1056(7) nm~3, Dc=1.445 Mg/m~3, Z=2, F(000)=492, μ=0.319 mm~(-1). 初步生物活性测试结果表明, 部分化合物具有较好的除草活性.

In order to find high active pesticide, nine novel compounds of N-substituted benzoyl-N'-substituted arylthiourea were synthesized starting from industrial acifluorfen and its intermediate. Their structures were characterized by IR, H-1 NMR spectra and elemental analysis. The single crystal structure of compound 4b was determined by X-ray diffraction analysis. The crystal belongs to triclinic with space group P-1, a=0.51588(19) nm, b=1.0766(4) nm, c=2.0596(8) mn, alpha=81.113(6)degrees, beta=89.702(6)degrees, gamma=78.131(6)degrees, V= 1.1056(7) nm(3), D-c=1.445 Mg/m(3), Z=2, F(000)=492, mu=0....
