novel class of bidentate (P,N) ligands is presented, the structures of which are characterized by three distinct elements of chirality. The stereoselective installation of the elements of central chirality (at the benzylic carbon and the phosphorus atom) depends on the size of the phosphorus substituent. Thermal inversion of the phosphorus center has been studied experimentally and further correlated
提出了一种新型的双齿(P,N)配体的改进合成方法,其结构以手性的三个不同元素为特征。中心手性元素(在苄基碳和磷原子上)的立体选择性安装取决于磷取代基的大小。已经对磷中心的热转化进行了实验研究,并通过DFT计算进行了进一步的关联。还研究了这些配体的潜力以及磷原子在醛(Pd)的不对称α-芳基化和烯丙醇(Ir)氢化中的作用。
