introduction of chiral anionic ligands. A novel method for the synthesis of monosubstituted, enantio- and diastereomericallypure titanocenes with C2-symmetry in the (RC5H4)2Ti fragment by reacting the methylated complexes with camphorsulfonic acid is presented. This study encompasses data from NMR and X-ray analysis as well as a mechanistic investigation with the aid of state of the art DFT calculations
通过引入手性阴离子配体实现未桥联取代二茂钛的构象锁定。提出了一种通过甲基化配合物与樟脑磺酸反应合成在(RC 5 H 4 ) 2 Ti片段中具有C 2对称性的单取代、对映体和非对映体纯二茂钛的新方法。这项研究包含来自 NMR 和 X 射线分析的数据,以及借助最先进的 DFT 计算进行的机械研究。
