含二芳胺基的吡啶甲酰胺的合成、晶体结构与除草活性（英文）
发布时间：2023-11-12 19:14
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)?,b=13.026(2)?,c=12.267(2)?;Z=4,V=1669.7(5)?3,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%。
