摘要: 用3,6-二取代苯氧基哒嗪与醇钠进行亲核取代反应的新方法合成19个3-烷基-6-取代苯氧基哒嗪.对目标化合物进行了pI50和盆栽除草活性的测试,部分化合物的活性高于对照药品马来酰肼.初步定量构效关系的结果表明:苯环3,4位上带有吸电子取代基以及增加分子的脂溶性对提高除草活性有利

关键词: 取代苯氧基哒嗪, 除草活性, 合成, 定量构效关系

Abstract: Aseries of3-alkoxyl-6-(substituted)phenoxypyridazines were synthesized in good yields by a novel synthetic approach, the nucleophilic reaction of3,6-bis (substituted)phenoxypyridazines with alkoxides.Their pI50value against barnyard grass and greenhouse activity against barnyard grass, common crabgrass, rape, amaranth were tested.The results showed that some of them exhibited a higher activity than MH.The primary quantitative sturcture activity relationship(QSAR) was discussed

Key words: Substituted)phenoxypyridazines, Herbicidal activity, Synthesis, QSAR
