Gold nanoparticles immobilized on N‐doped ordered mesoporous carbon: An efficient catalyst for A3 and KA2 coupling reactions

Applied Organometallic Chemistry, Год журнала: 2023, Номер 37(4)

Опубликована: Фев. 14, 2023

Gold nanoparticles immobilized on egg yolk biomass derived N ‐doped ordered mesoporous carbon (Au@OMC) were prepared by nano‐casting process using SBA‐15 template and carbonization, followed removing silica moiety of SBA‐15, then immobilization Au nanoparticles. Synthesized Au@OMC was characterized XRD, SEM, TEM, EDS, XPS, DLS, BET analysis, revealing the successful surface OMC material. exhibited high catalytic activity for three‐component A3 coupling reaction between aldehydes, amines, phenylacetylene to furnish propargyl amines. Also, KA2 ketones, efficiently performed system. Recyclability studies indicated that recovered catalyst can be reused five runs without considerable changes in activity. The leaching experiment revealed there is no into solution.

Abstract The versatility of aza- and oxa-heterocyclic compounds has garnered significant attention in recent times. A large number currently approved pharmaceutical products include nitrogen- oxygen-containing heterocycles. Recent nanotechnological developments have propelled an upsurge the applications nanocatalysis for heterocyclic synthesis. Metal nanoparticles (MNPs) emerged as promising catalysts synthesis oxa-heterocycles owing to their unique physicochemical properties. Various MNPs including gold, silver, nickel palladium been evaluated catalytic activities different reaction types, cyclisation, coupling, hydrogenation oxidative transformations. exhibited remarkable efficiency when utilised under optimal conditions. These showcased high reusability recyclability, yielding satisfactory amounts desired compound. present work provides a detailed overview advances area MNP-assisted synthetic construction oxa-heterocycles, published during previous calendar year, 2022. review serves valuable resource also paves way future investigations development novel strategies heterocycle 1 Introduction 2 Nanocatalysis 3 Aza- Oxa-Heterocycle Synthesis Catalysed by 3.1 AuNPs 3.2 CuNPs 3.3 CoNPs 3.4 FeNPs 3.5 NiNPs 3.6 PdNPs 3.7 PtNPs 3.8 SiNPs 3.9 ZnNPs 3.10 Bimetallic NPs 3.11 Other 4 Summary Outlook

Selective Hydrogenation of N-Heterocyclic Carboxylate over Nitrogen-Doped Porous Carbon-Supported Nano-Ni

ACS Applied Nano Materials, Год журнала: 2024, Номер 7(8), С. 9195 - 9209

Опубликована: Апрель 10, 2024

The hydrogenation of nitrogen-containing heterocyclic compounds and their derivatives to obtain the corresponding valuable products is great practical significance. In this work, a highly active selective Ni/NC catalyst was developed by utilizing melamine-modified high-specific surface carbon (NC) as carrier for nickel nanoparticles (NPs), which showed excellent catalytic activity in methyl nicotinate, where first used reaction (selective nicotinate). It found that nitrogen species on NC significantly promoted decomposition precursor high dispersion nano-Ni, effectively affected agglomeration metal, resulting distribution metal with smaller particle size. nicotinate under mild conditions (130 °C, 3 h), conversion reached optimal over 10% Ni/NC-1-M-I-300, 98.5% selectivity methylpiperidine-3-carboxylate 97.2%. After 5 recycles, maintained 95.4% nicotinate. has good substrate adaptability N-heterocyclic carboxylate, O-heterocyclic aromatic carboxylate.
