Abstract 2,4-Bis (4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (Lawesson's Reagent) reacts with glycinamides (2a-m) in benzene at 55 ∼ 60°C to give 1,3,2-diazaphospholidin-4-thone-2-sulfides (3a-m). The structure of the products has been confirmed by elementary analyses, NMR, IR, MS and X-ray diffraction. The result of preliminary bioassay indicates that some of the compounds prepared
摘要 2,4-双(4-甲氧基苯基)-1,3,2,4-二硫代二膦烷-2,4-二硫化物(Lawesson 试剂)与甘氨酰胺(2a-m)在苯中在 55 ∼ 60°C 下反应生成 1 ,3,2-diazaphospholidin-4-thone-2-sulfides (3a-m)。产物的结构已通过元素分析、核磁共振、红外、质谱和X射线衍射证实。初步生物测定结果表明,所制备的部分化合物对rap具有较高的选择性除草活性。
