AbstractA general procedure has been developed for the rapid synthesis of 8-aryl-7H-acenaphtho[1,2-d]imidazoles in high yields using Fe3O4 NPs@GO@C4H8SO3H as a green and recyclable magnetic nanocatalyst under reflux conditions. The nanocatalyst was prepared and characterized by FT-IR, XRD, and EDX data. A variety of aromatic aldehydes underwent condensation with NH4OAc and acenaphthenequinone to give

8-Aryl-7H-acenaphtho[1,2-d] imidazoles were produced by a catalytic process utilizing diethanolamine sulfate-functionalized graphene oxide. The process was implemented using acenaphthoquinone, ammonium acetate, and aromatic aldehydes via a one-pot reaction under solvent-free conditions. The applied catalyst smoothly catalyzed the reactions at high yields. The developed catalyst offered several advantages
