The catalyst was characterized <i>via</i> FT-IR, SEM, XRD, EDS, TGA, BET and VSM. This new catalyst was demonstrated to be highly effective in the preparation of chromenpyrimidines. Atom economy, low catalyst loading, reusable catalyst, applicability to a wide range of substrates and high product yields are some of the important features of this protocol.RSC advances37344-37354https://www.ebi.ac.uk/biostudies/studies/S-EPMC9075579biostudies-literatureCo₃O₄/NiO@GQD@SO₃H nanocomposite as a superior catalyst for the synthesis of chromenpyrimidines.PMC9075579Safaei-Ghomi JOmidshafiei ZfalseCo₃O₄/NiO@GQD@SO₃H nanocomposite as a superior catalyst for the synthesis of chromenpyrimidines.A three-component reaction involving aromatic aldehydes, 6-amino-1,3-dimethyluracil and 4-hydroxycoumarin was achieved in the presence of the Co₃O₄/NiO@GQD@SO₃H nanocomposite as a highly effective heterogeneous catalyst to produce chromenpyrimidines.
