The development of catalyst based on porous crystalline materials (PCM) constructed from metal ions or clusters and multidentate organic ligands is a topic of great interest. In view of the Lewis acidic and basic properties of PCMs, we report for the first time that MIL-101(Cr) works as a synergistic catalyst for the reduction of imines with trichlorosilane as the hydrogen source. Both ketimines and
基于由金属离子或簇和多齿有机配体构成的多孔晶体材料(PCM)的催化剂的开发是非常感兴趣的主题。鉴于PCM的Lewis酸性和碱性,我们首次报道MIL-101(Cr)作为三氯硅烷为氢源还原亚胺的协同催化剂。此方案可耐受酮亚胺和醛亚胺,从而以中等至高收率得到相应的胺。操作简便以及反应条件温和,使该方案成为合成胺的有吸引力的方法。此外,还通过接枝手性N实现了手性MOF CMIL-101-甲酰基脯氨酸衍生物的开放金属位点。此外,就产率和对映选择性而言,CMIL-101表现出与同类均相催化剂相当的催化性能。
