【摘要】 嘧啶水杨酸类化合物除草剂是通过优化嘧啶磺酰脲类化合物结构合成的,用2种方法合成24个新型的具有除草活性的6-氯-2-嘧啶氧基苄胺类化合物。温室盆栽试验结果表明,在75ga.i./hm2用量下,24种化合物都具有良好的除草活性。更多还原

【Abstract】 24 novel 6-chloride-2-pyrimindinyloxy benzylamine derivatives with weeding activity were synthesized by two different routes.The structures of the products were characterized by 1H NMR,Preliminary bioassay by greenhouse pot-trials indicates that all the 24 compounds have good herbicidal activity at the dosage 75 g a.i./hm2.更多还原
