The reaction of racemic orthomercurated (η6-arene)tricarbonylchromium complexes with bis[(η6-cymene)ruthenium(II)dichloride] affords the corresponding dinuclear (Cr,Ru) products with moderate yields, which have been satisfactorily characterized by X-ray diffraction analysis. The synthesis of nonracemic orthomercurated (η6-arene)tricarbonylchromium complexes has been attempted starting from enantio-enriched
外消旋orthomercurated(η反应6 -arene)tricarbonylchromium络合物与二[(η 6 -cymene)合钌(II)二氯化物],得到相应的双核(铬,钌)产品具有适中的产率,已令人满意,其特征在于X-射线衍射分析。的非外消旋orthomercurated的合成(η 6 -arene)tricarbonylchromium络合物已经尝试从对映体富集的均聚物和杂的Pd(II)配合物bischelated开始。的两种对映体邻-汞化2- [三羰基(η 6 -苯基)铬]吡啶通过与升汞bischelated一个杂的Pd(II)的反应合成了2。两种汞(II)配合物也与双[[η6 -cymene)合钌(II)二氯化物],并且得到相应的非外消旋(铬,钌)的产品,以对映体过量范围从82至89%所建议1 1 H NMR在BINPHAT阴离子的存在下进行分析。
