合成了2苯胺1 ,3 ,5三嗪的一系列衍生物 ,并评价了它们的除草活性。首先研究了三嗪环上的取代 ,结果表明4甲基6三氟甲基衍生物显示高的除草活性 ,其次研究了2苯胺4甲基6三氟甲基1 ,3 ,5三嗪的苯环取代 ,结果表明苯环上的3或4卤素衍生物显示更高的除草活性。在盆载试验中表现高除草活性的2(3氯苯胺基)4甲基6三氟甲基1 ,3 ,5三嗪和2(4氯苯胺基)4甲基6三氟甲基1 ,3 ,5三嗪 ,其PET(光合电子通道)抑制活性也比除草剂西玛津和莠去津的高。
A series of derivatives of 2 aniline 1,3,5 triazine were synthesized and their herbicidal activities were evaluated. The first study of the triazine ring substitution, the results showed that the 4 methyl 6 trifluoromethyl derivatives showed high herbicidal activity, followed by the study of 2 aniline 4 methyl 6 trifluoromethyl 1,3,5 triazine benzene Ring substitution, the results showed that 3 or 4 halogen derivatives on the benzene ring showed higher herbicidal activity. 2 (3 chloroanilino) 4 methyl 6 trifluoromethyl 1,3,5 triazine and 2 (4 chloroanilino) 4 methyl 6 trifluoromethyl 1 which showed high herbicidal activity in the pot test, 3, 5 triazine, its PET (photosynthetic electron channel) inhibitory activity than the herbicides simazine and atrazine high.
