pentadentate bis(oxazolines) has been synthesized using a modular approach that readily provides access to this ligand class. This ligand allows the controlled transfer of carbon-centered to octahedral, metal-centered chirality, as demonstrated both in the solid state as well as in solution. The characteristic CD band has been identified for dicationic, octahedral transition metal complexes with the Δ2-configuration
五齿双(恶唑啉)的第一个实例已使用模块化方法合成,该方法可轻松获得该配体类别。如在固态以及在溶液中所证实的,这种配体允许以碳为中心的控制性转移到以金属为中心的八面体,以手性为中心。的特征的CD带已被确定为与所述Δ双阳离子,八面体的过渡金属络合物2 -构型。
