选择3-(2-氯-4-三氟甲基苯氧基)苯甲酸为起始原料,经酰氯化,再与乙醇反应成酯,然后和水合肼反应,最后与芳香醛缩合,合成了10个未见文献报道的3-(2-氯-4-三氟甲基苯氧基)苯甲酰腙4.通过IR,1H NMR,EI-MS,元素分析等方法对所合成的化合物进行了结构表征.代表化合物4-氯苯亚甲基-3-(2-氯-4-三氟甲基苯氧基)苯甲酰腙(4f)经单晶X衍射证实了结构.并初步测定了所合成化合物的杀菌和除草活性.结果表明:部分测试化合物在50 mg/L浓度下对水稻纹枯菌和黄瓜灰霉菌具有优良的抑制效果,在100 mg/L浓度下对油菜和稗草的根显示一定的抑制效果.
3- (2-Chloro-4-trifluoromethylphenoxy) benzoic acid is chosen as the starting material, which is acyl chlorinated and reacts with ethanol to form ester, which is then reacted with hydrazine hydrate and finally condensed with aromatic aldehyde to synthesize 10 unreported 3- (2-chloro-4-trifluoromethylphenoxy) benzoyl hydrazone 4. The synthesized compounds were characterized by IR, 1H NMR, EI-MS and elemental analysis The structure was confirmed by single crystal X-ray diffraction (XRD) on behalf of the compound 4-chlorobenzylidene-3- (2-chloro-4-trifluoromethylphenoxy) benzoylhydrazone Bactericidal activity and herbicidal activity of the synthesized compounds were tested.The results showed that some of the compounds tested showed good inhibitory effects on R. solanacearum and Botrytis cinerea at a concentration of 50 mg / The root shows some inhibitory effect.
