以4-氰基苯酚为起始原料,在4-烷氧基/苄氧基苯甲脒结构基础上,设计合成了5个4-烷氧基/苄氧基苯基四唑及17个新型2-取代-5-(4-烷氧基/苄氧基)苯基噁二唑类化合物,通过元素分析、1H NMR和MS对所合成的新化合物进行了结构表征.初步除草活性测试结果表明,部分化合物对双子叶油菜和单子叶稗草表现出较好的生长抑制活性.
Based on the 4-alkoxy / benzyloxybenzamidine structure, 5 4-alkoxy / benzyloxyphenyl tetrazole and 17 new The structure of 2-substituted 5- (4-alkoxybenzyloxy) phenyl oxadiazoles was characterized by elemental analysis, 1H NMR and MS.The results of preliminary herbicidal activity test , Some of the compounds showed good growth inhibitory activity on dicotyledonous and barnyardgrass.
