A new family of chiral diazaphospholidines is readily accessible by phosphorylating commercially available (S)-1,1'-binaphthyl-2,2'-diamine. NMR spectroscopy, mass spectrometry and X-ray crystallographic analysis reveal their unique structures. In preliminary studies these novel monodentate P-ligands were tested in Rh-catalyzed hydrogenation and hydroformylation (31% ee) reactions. The modular nature
通过磷酸化市售的 (S)-1,1'-binaphthyl-2,2'-二胺,可以很容易地获得一个新的手性二氮杂磷脂家族。核磁共振光谱、质谱和 X 射线晶体学分析揭示了它们独特的结构。在初步研究中,这些新型单齿 P-配体在 Rh 催化的氢化和加氢甲酰化 (31% ee) 反应中进行了测试。配体的模块化特性允许进一步的结构多样性。
