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

چکیده مقاله

Here, we prepared an efficient and reusable catalyst by stepwise post-synthetic modification of surface nitrogen-enriched Cu(BDC[sbnd]NH₂) metal-organic frameworks (MOFs) and used it as a catalyst for the preparation of [Cu(BDC[sbnd]NH₂) -AuNTf₂]. Catalytic performance results of the [Cu(BDC[sbnd]NH₂)-AuNTf₂] catalyst showed high efficiency in modulating the microenvironment of AuNTf₂ Nanoparticles. Successful preparation of [Cu(BDC[sbnd]NH₂)-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. © 2023 Elsevier B.V.
