【摘要】 [目的]进一步寻找高效的磺酰脲类除草剂。[方法]参考经典磺酰脲类结构,将含硫脲和三氟甲基分别引入,对2类化合物进行探索性研究。[结果]共合成10个未见文献报道的新型磺酰脲化合物,通过1H NMR、高分辨质谱确定其结构。[结论]目标化合物经盆栽试验,结果表明化合物Ia~Id、IIa、IIf有较好的除草活性。为以后的实验和开发提供了一定的基础。更多还原

【Abstract】 [Aims] The study aims to search for novel high-effective sulfonylurea herbicides. [Methods] Title compounds were designed by introducing a thiourea bridge or trifluoromethyl moiety respectively into the benzene ring.[Results] Ten novel compounds were synthesized and characterized by 1H NMR and H RMS. [Conclusions] Bioassay showed that Ia-Id,IIa and IIf exhibited comparatively good herbicidal activity.更多还原
