合成了9个新型邻甲酰胺基苯甲酰胺衍生物,其结构经1H NMR进行确证。初步杀虫、杀螨活性测试表明所合成的化合物在1 000 mg/L浓度下对磷翅目的粘虫(Mythimna separata)有100%的致死率。在500 mg/L浓度下,大多化合物对同翅目的蚕豆蚜(Aphis fabae)以及稻黑尾叶蝉(Nephotettix cincticeps)具有明显活性,如化合物3-溴-1-(3-氯-2-吡啶基)-N-[4-氯-2-甲基-6-[((3,3-二氯烯丙氧基)氨基)羰基]苯基]-1H-吡唑-5-甲酰胺(14c)对蚕豆蚜的致死率达到89.29%;化合物14b对叶蝉的致死率达到81.82%。在500 mg/L浓度下,所合成化合物对蜱螨目棉红蜘蛛(Tetranchus urticae)没有表现出明显活性。
Nine novel o-formamidobenzamide derivatives were synthesized and their structures were confirmed by 1H NMR. The preliminary insecticidal and acaricidal activity tests showed that the synthesized compounds had a 100% lethality to Mythimna separata at a concentration of 1 000 mg / L. At the concentration of 500 mg / L, most of the compounds have obvious activity on the homopteran Aphis fabae and Nephotettix cincticeps, such as the compound 3-bromo-1- (3-chloro-2-pyridine (14,3-dichloro-propoxy) amino) carbonyl] phenyl] -1H-pyrazole-5-carboxamide (14c ) To A. faba reached 89.29%. Compound 14b lethal to leafhopper reached 81.82%. At the concentration of 500 mg / L, the synthesized compounds did not show obvious activity against Tetranchus urticae.
