Phthalic acid diamides have received considerable interest in agricultural chemistry due to a novel action mode, extremely high activity against a broad spectrum of lepidopterous insects, low acute toxicity to mammals, and environmentally benign characteristics. A series of phthalic acid diamides (4I−4IV) with the CF3 group at meta position on the aniline ring were synthesized. Their structures were
邻苯二甲酸二酰胺由于其新颖的作用方式,对多种鳞翅目昆虫的极高活性,对哺乳动物的低急性毒性以及环境友好的特性,已在农业化学中引起了广泛的关注。合成了一系列在苯胺环的间位具有CF 3基的邻苯二甲酸二酰胺(4I - 4IV)。它们的结构通过1 H NMR和13 C NMR(或元素分析)进行表征。N 2- [1,1-二甲基-2-(甲硫基)乙基] -3-碘-N 1- [3-氟-5-(三氟甲基)苯基] -1,2-苯二甲酰胺的结构(4If通过X射线衍射晶体学测定)。评价了它们对小菜蛾的杀虫活性。结果表明,某些标题化合物对小菜蛾具有优异的杀幼虫活性,而杀幼虫活性的改善需要母体结构中取代基的合理组合,这为进一步研究结构修饰提供了一些提示。
