The synthesis of the chiral polyfunctional diphosphine salenophos 1 is described. The new ligand bearing hard and soft coordination sites chelates titanium(IV) as well as palladium(II) in a defined manner provided a certain order during the introduction of the two metals was kept. In this way the first chiral early-late heterobimetallic complex could be synthesized. It was fully characterized by NMR
描述了手性多官能二膦salenophos 1的合成。带有硬和软配位点的新配体以一定的方式螯合钛(IV)和钯(II),只要在引入两种金属时保持一定顺序即可。这样,可以合成第一个手性早晚异双金属配合物。它已通过NMR光谱和X射线结构分析得到充分表征。异双金属配合物的显着特征是钯上膦基的反式配位以及Ti与Pd之间的距离大于4.13Å。
