  Encapsulation of Transition Metal Catalysts by Ligand-Template Directed Assembly

  摘要：

  Encapsulated transition metal catalysts are presented that are formed by templated self-assembly processes of simple building blocks such as porphyrins and pyridylphosphine and phosphite ligands, using selective metal-ligand interactions. These ligand assemblies coordinate to transition metals, leading to a new class of transition metal catalysts. The assembled catalyst systems were characterized using NMR and UV-vis spectroscopy and were identified under catalytic conditions using high-pressure infrared spectroscopy. Tris-3-pyridylphosphine binds three mesophenyl zinc(II) porphyrin units and consequently forms an assembly with the phosphorus donor atom completely encapsulated. The encapsulated phosphines lead exclusively to monoligated transition metal complexes, and in the rhodium-catalyzed hydroformylation of 1-octene the encapsulation of the catalysts resulted in a 10-fold increase in activity. In addition, the branched aldehyde was formed preferentially (l/b = 0.6), a selectivity that is highly unusual for this substrate, which is attributed to the encapsulation of the transition metal catalysts. An encapsulated rhodium catalyst based on ruthenium(II) porphyrins and tris-meta-pyridyl phosphine resulted in an even larger selectivity for the branched product (l/b = 0.4). These encapsulated catalysts can be prepared easily, and various template ligands and porphyrins, such as tris-3-pyridyl phosphite and ruthenium(l I) porphyrins, have been explored, leading to catalysts with different properties.

  用于模板辅助双齿配体形成的刚性双锌（II）连体构造基块及其在催化中的应用

  摘要：

  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。
