Stabilization of Au-nanoparticle-decorated postsynthesis-modified Cu(BDC-NH2) MOF as a reusable heterogeneous catalyst in an intermolecular hydroamination of allenamides with arylamines

Abstract

Here, we prepared an efficient and reusable catalyst by stepwise post-synthetic modification of surface nitrogen-enriched Cu(BDCNH2) metal-organic frameworks (MOFs) and used it as a catalyst for the preparation of [Cu(BDCNH2) -AuNTf2]. Catalytic performance results of the [Cu(BDCNH2)-AuNTf2] catalyst showed high efficiency in modulating the microenvironment of AuNTf2 Nanoparticles. Successful preparation of [Cu(BDCNH2)-AuNTf2] catalyst has been proven by various techniques, including FT-IR, XRD, SEM, BET, EDS, ICP, and TGA. The synthesis of allylamino E-enamides with good yield and high stereoselectivity was carried out under mild conditions in the presence of AuNTf2 Nanoparticle catalysis. Clean method, easy catalyst manufacturing, high efficiency, and recyclability are the most important advantages of this procedure.
