“…In this study, we continue the development of synthesizing MNPs as catalysts for multicomponent reactions (MCRs) with a focus on their environmentally‐friendly properties 45–47 . Particularly, we report on the arrangement of CoFe₂O₄@THAM@PHG‐SO₃H and explore its adequacy as a reusable nanocatalyst within the amalgamation of 3,4‐dihydropyranochromene through a three‐component response including aromatic aldehydes ( 1 ), 4‐hydroxycoumarin ( 2 ), and malononitrile ( 3 ).…”

In this study, we have developed a new environmentally‐friendly magnetic nanocatalyst by treating CoFe₂O₄ magnetic nanoparticles with chlorosulfonic acid, tris(hydroxymethyl)aminomethane (THAM), 1,2‐dichloroethane, and phloroglucinol (PHG). They confirmed the synthesis of the catalyst using various techniques such as FT‐IR, SEM, MAP, EDS, XRD, TGA, DTA, and VSM. The researchers then evaluated the catalytic efficiency of the nanocatalyst in two reactions: the synthesis of 3,4‐dihydropyranochromenes from the reaction among aromatic aldehydes, 4‐hydroxycoumarin, and malononitrile, and the synthesis of chromeno[3,4‐b]quinoline‐6‐ones from the reaction among aniline, 4‐hydroxycoumarin, and aromatic aldehydes.
