【摘要】 采用活性基团拼接原理,分别以2-氯-5-氯甲基吡啶和2-氯-5-氯甲基噻唑为原料,经过氮烷基化和加成反应,得到系列含吡啶甲基或噻唑甲基的哌嗪类化合物.初步测试结果表明:部分化合物表现出较弱的除草活性和杀豆蚜活性,但对孑孓显示出较高的的杀灭活性,其中4f在50mg/L的浓度下对孑孓的杀死率可达100%.更多还原

【Abstract】 According to the principle of combination of active groups, a series of piperazine derivatives containing pyridinemethyl/thiazolemethyl were designed and synthesized from 2-chloro-5-(chloromethyl) pyridine or 2-chloro-5-(chloromethyl)thiazole via N-alkylation and addition reactions. Some compounds showed weak herbicidal activity and insecticidal activity against Aphis fabae but good insecticidal activity against Culex pipiens, among which compound 4f exhibited 100% mortality against Culex pipiens at 50 mg/L.更多还原
