| 中文摘要: |
| 通过三步反应合成了新化合物N-[2-（苯胺基）苯基]-2-甲氧基吡啶-3-甲酰胺（C19H17N3O2），其结构通过1H NMR、13C NMR和ESI-MS表征，晶体结构通过X-射线单晶衍射解析。其晶体属单斜晶系，空间群为P 1 21/n 1，晶胞参数为：a=10.6329（18）Å，b=13.026（2）Å，c=12.267（2）Å；Z=4，V=1669.7（5）Å3，Mr=319.35，Dc=1.270 mg/m3，S=1.027，F（000）=672，μ（Mo Kα）=0.085 mm-1。分子间存在氢键N（3）-H（3）…O（2）对晶体结构起到稳定的作用。初步除草活性试验表明，化合物在3000g a.i/hm2剂量时对稗草的茎叶处理抑制率为91.81%。 |
| 英文摘要: |
| The novel compound N-[2-(phenylamino) phenyl]-2-methoxyl pyridine carboxamide (3) was synthesized via three steps, and its structure was characterized by 1H NMR, 13C NMR, ESI-MS and X-ray diffraction. The crystal structure of this compound belongs to monoclinic system, space group P 1 21/n 1 with a=10.6329(18), b=13.026(2), c=12.267(2)Å, Z=4, V=12.267(2)Å3, Mr=319.35, Dc=1.270mg/m3, S=1.027, F(000)=672, μ (Mo Kα)=0.085 mm-1. X-ray crystal structure indicated the presence of intermolecular N(3)-H(3)…O(2) hydrogen bond in the molecule, which plays an important role in stabilizing the crystal structure. The preliminary herbicidal activity bioassay showed that the titled compound 3 had 91.81% inhibition against Barnyard grass at 3000 g a.i/hm2. |
