Synthesis of pyrido[2,3‐d:5,6‐d′]dipyrimidines using CuFe₂O₄/KCC‐1/PMA as a novel and efficient nanocatalyst under solvent‐free conditions

Abstract

In this research, the synthesis of pyrido[2,3‐d:5,6‐d′]dipyrimidines by CuFe2O4/KCC‐1/PMA magnetic nanoparticles was reported. Synthesis of pyrido[2,3‐d:5,6‐d′]dipyrimidines was performed under solvent‐free conditions with good to excellent yields. The prepared nanocatalyst was synthesized in three steps and also was characterized by Fourier transform infrared (FT‐IR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy‐dispersive X‐ray spectroscopy (EDX), X‐ray diffraction (XRD), vibrating sample magnetometry (VSM), and N2 adsorption–desorption measurement (Brunauer–Emmett–Teller [BET]) analyses. In addition, the reusability studies of CuFe2O4/KCC‐1/PMA showed that the recovered catalyst could be used for several times.

Stabilization of Palladium-Nanoparticle-Decorated Postsynthesis-Modified Zr-UiO-66 MOF as a Reusable Heterogeneous Catalyst in C–C Coupling Reaction

“…The tendency of the metal nanoparticle for aggregation in solvents makes it urgent to use heterogeneous supports for their cost-effective, green, and reusable applications. − The aggregation of metal NPs decreases their surface area, resulting in diminishing or even quenching of the catalytic activities. Heterogenous supports not only can prevent aggregation of the NPs but also can boost their catalytic performance or add some new features to the resulting composite. − …”

Novel carbazolyl–thiazolyl–chromone and carbazolyl–thiazolyl–pyrazole hybrids: synthesis, cytotoxicity evaluation and molecular docking studies

“…MCRs streamline the creation of medicinal drugs thanks to their simplicity, minimal waste, high productivity, excellent yields, and straightforward workup processes. [28][29][30][31] Furthermore, ultrasound-assisted organic synthesis is an effective and has a number of advantages over traditional synthesis techniques, including the ability to decrease both time and electricity, and a shortened work-up procedure. [32][33][34][35][36][37] In addition, ultrasound irradiation as a simple instrument and clean synthetic procedure can give a good yield of product.…”

Stabilization of Pd NPs over the surface of β-cyclodextrin incorporated UiO-66-NH2 for the C–C coupling reaction

“…The role of β-CDNs can be explained on the base of its capability to form inclusion complex with substrates and bringing them in the vicinity of the catalytic active sites. 12,13 Also β-cyclodextrin can activate variety of organic compounds like aldehydes, ketones, anhydride, oximes, amines, nitriles and increase the rate of reactions. 14,15 Here, novel β-cyclodextrin (β-CD)@1,4-dibromo butane@functionalized UiO-66-NH 2 /Pd-NPs composite was in situ prepared using β-CD functionalized MOF (Zr) and Pd-NPs, and C–C coupling reactions to promote formation coupling desired was developed based on the composite.…”
