Post-synthetically modified MOF for the A 3 -coupling reaction of aldehyde, amine, and alkyne

A new heterogeneous NHC catalyst (Ag-NHC-MOF) was synthesized by the post-synthetic modification of an azolium-containing metal–organic framework. The structure of the catalyst was well defined and fully characterized using various techniques such as PXRD, FE-SEM, HR-TEM, XPS, FT-IR, TGA, BET, 1 H-N...

Summary:A new heterogeneous NHC catalyst (Ag-NHC-MOF) was synthesized by the post-synthetic modification of an azolium-containing metal–organic framework. The structure of the catalyst was well defined and fully characterized using various techniques such as PXRD, FE-SEM, HR-TEM, XPS, FT-IR, TGA, BET, 1 H-NMR, 13 C-NMR, EDS, and ICP. The catalyst showed an excellent activity towards the A 3 -coupling reaction with a broad substrate scope. The A 3 -coupling reaction was performed under ambient conditions and full conversion was reached within just 1 hour for the model reaction. The heterogeneous silver NHC MOF (Ag-NHC-MOF) catalyst can be recycled and reused at least four times without a significant loss of activity. In comparison with previously reported heterogeneous catalysts applied for the A 3 -coupling reaction, the Ag-NHC-MOF demonstrates a superior performance for the A 3 -coupling reaction.
