  Versatile Approach toward the Self-Assembly of Heteromultimetallic Salen Structures

  摘要：

  A general route is presented toward the template-directed preparation of self-assembled heteromultimetallic salen structures using noncovalent coordinative metal-ligand interactions. Various higher order assemblies have been studied in detail using a combination of NMR spectroscopy and X-ray crystallography.

• Self-Assembly of a Confined Rhodium Catalyst for Asymmetric Hydroformylation of Unfunctionalized Internal Alkenes
  作者：Tendai Gadzikwa、Rosalba Bellini、Henk L. Dekker、Joost N. H. Reek

  DOI：10.1021/ja211455j

  日期：2012.2.15

  A chiral supramolecular ligand has been assembled and applied to the rhodium-catalyzed asymmetric hydroformylation of unfunctionalized internal alkenes. Spatial confinement of the metal center within a chiral pocket results in reversed regioselectivity and remarkable enantioselectivities.

  We report the template-induced formation of chelating heterobidentate ligands by the selective self-assembly of two different monodentate ligands on a rigid bis-zinc(II)-salphen template with two identical binding sites; these templated heterobidentate ligands induce much higher enantioselectivities (up to 72% ee) in the rhodium-catalyzed asymmetric hydroformylation of styrene than any of the corresponding homobidentate ligands or non-templated mixed ligand combinations (up to 13% ee).

  我们报道了在一个具有两个相同结合位点的刚性双锌(II)沙芬模板上，通过选择性自组装两种不同的单齿配体，诱导形成螯合的异双齿配体；这些模板化的异双齿配体在铑催化的苯乙烯不对称氢甲酰化中引发了远高于任何相应同双齿配体或非模板化混合配体组合的对映选择性（最高可达72% ee），而后者仅为最高13% ee。

  salphen template with two identical binding sites was studied. Using UV-vis, NMR-spectroscopy and X-ray analysis the formed structures were unambiguously proven. The application of these templated bidentate ligands in transition metal catalysis showed, in most cases, typical bidentate character. Compared to previous work based on a more flexible bis-zinc(II) porphyrin template, the current catalytic data

  研究了在具有两个相同结合位点的刚性双锌（II）连字模板上通过两个单齿吡啶基磷配体的选择性自组装，模板诱导的螯合双齿配体的形成。使用紫外可见光，核磁共振波谱和X射线分析可以清楚地证明所形成的结构。在大多数情况下，这些模板化的双齿配体在过渡金属催化中的应用显示出典型的双齿特征。相比基于一个更灵活的双-锌（以前的工作II）卟啉模板，电流催化数据表明，模板的刚性不是所施加的反应条件下的区域选择性和对映选择性的改善的重要因素。
• Up to four phenoxyl radicals coordinated to two metal ions in copper and zinc complexes?

  Neutral copper(II) and zinc(II) complexes of the mono- and dinucleating Schiff base ligands (2,4-di-tert-butyl-6-(2-[(3,5-di-tert-butyl-2-hydroxy-benzylidene)-amino]-phenylimino}-methyl)-phenol) and (2,4-di-tert-butyl-6-(2,4,5-tri-[(3,5-di-tert-butyl-2-hydroxy-benzylidene)-amino]-phenylimino}-methyl)-phenol) respectively were synthesized and characterized. The monometallic complex can be oxidized into a mono and a dication, while oxidation of the dimetallic one affords up to a tetracation. Whatever the ligand and metal are, oxidation takes place at the phenolate moieties, which were oxidized into coordinated phenoxyl radicals, i.e. the oxidation locus is not correlated to the ligand nuclearity. These results could be rationalized with previous ones by considering the hybridization of the coordinating nitrogens and the nature of the O-donor groups.
