  Enantiomeric Resolution of Asymmetric-Carbon-Free Binuclear Double-Stranded Cobalt(III) Helicates and Their Application as Catalysts in Asymmetric Reactions

  摘要：

  A series of double-stranded binuclear helicates [Co-2-(H1)(2)](4+), [Co-2(H2)(2)](4+), and [Co-2(H3)(2)](4+), derived from mono-deprotonated bis-pyridyl hydrazine-based ligands of H(2)1, H(2)2, and H(2)3 with one, two, and three -CH2 spacers, were obtained. These asymmetric-carbon-free racemic helicates were separated into their Delta Delta and Lambda Lambda enantiomers. The resolved helicates were examined for the first time as enantioselective catalysts in asymmetric benzoylation and nitroaldol reactions.

  analysis confirms the formation of one‐dimensional coordination polymer with zigzag fashion in CP‐1 and ladder chain CP‐2. Both the CPs are applied as catalysts to synthesize various cyclic carbonates from epoxides and carbon dioxide. The catalysts are giving better conversion under solvent‐free and additive‐free condition using 10 bar CO2 and 100 °C as optimized pressure and temperature. The detailed

  与Zn（II）和Cd（II）络合的多齿配体H 2 L提供了一维聚合物网络。这些配位聚合物（CP）CP-1和CP-2分别含有Zn（II）和Cd（II）金属。单晶结构分析证实在CP-1和梯形链CP-2中形成了锯齿形的一维配位聚合物。两种CP均用作催化剂，由环氧化物和二氧化碳合成各种环状碳酸酯。使用10 bar CO 2在无溶剂和无添加剂条件下，催化剂可提供更好的转化率和100°C作为最佳压力和温度。提出一级动力学的详细动力学实验表明，针对该催化转化计算了活化能（Ea）。
