Postsynthetic modification of metal-organic framework as a highly efficient and recyclable catalyst for three-component (aldehyde-alkyne-amine) coupling reaction

A MOF-supported Cu(I) catalyst bearing N,O-chelating ligand was prepared through postsynthetic modification of IRMOF-3 and used as an efficient heterogeneous catalyst for three-component coupling reaction of aldehyde, alkyne, and amine. The catalyst exhibited both high catalytic activity and stability for the reaction and the framework of Cu(I) catalyst was mainly maintained after the catalyst was reused for four times.
