三个手性二铑的配位聚合物的Rh 2 -L Ñ(Ñ = 1-3)已合成经由二铑的Rh三氟之间的配体交换2(TFA)4和不同尺寸的手性二羧酸衍生自大号-叔-亮氨酸。SEM图像表明Rh 2 -L n(n = 1-3)聚合物具有层状结构。XPS数据表明,在聚合物的合成过程中,铑在二铑节点中的氧化态得以保持。FTIR,1 H→ 13进一步表征了配位聚合物C CP MAS NMR和19 F MAS NMR光谱可证明通过配体交换形成了聚合物。尽管定量19 F MAS NMR光谱显示配位聚合物中配体取代不完全,但这些催化剂在苯乙烯与重氮恶唑之间的不对称环丙烷化反应中显示出出色的活性和选择性。特别地,对映体选择性已经显著与先前设计的二铑的配位聚合物,其是从衍生自芳族二羧酸的合成相比提高大号-苯丙氨酸。同时,二茂金属聚合物可以容易地再循环五次而不会显着降低其催化效率。

Design and characterization of novel dirhodium coordination polymers – the impact of ligand size on selectivity in asymmetric cyclopropanation
synthesized via ligand exchange between dirhodium trifluoroacetate Rh2(TFA)4 and differently sized chiral dicarboxylic acids derivedfrom L-tert-leucine. SEM images indicate that the Rh2–Ln (n = 1–3) polymers have a lamellar structure. XPS data demonstrate that the oxidation state of rhodium in the dirhodium nodes is maintained during the synthesis of the polymers. The coordination polymers have been further
