| 摘 要： | 为了寻找新的高效烟碱类杀虫剂,用异氰酸酯与2-硝基亚氨基咪唑烷反应,得到10个含硝基亚氨基咪唑烷脲类新化合物,其结构均通过IR、1H NMR和元素分析确认。初步的生物活性试验结果表明, 3 号化合物在0.1 kg/hm2 时对马唐Digitaria sanguinalis的抑制率为64.5%, 6 号化合物在0.2 mg/L时对豆蚜Aphis craccivora Koch的致死率为67％。

| Abstract: | Ten substituted phenyl urea derivatives containing 2-(nitroimino )imidazolidine were synthesized from substituted phenyl isocyanate. Their structures were (confirmed) by IR, ()~1H NMR and elemental analysis. Preliminary bioassay showed that the (inhibitory) rate of compound 3 to Digitaria sanguinalis reached (64.5%) at (0.1 kg/hm~2,) and lethal of compound 6 to Aphis (craccivora) Koch reached 67%. |
