An efficient green approach for the synthesis of N-cyclohexyl-3-aryl-quinoxaline-2-amine derivatives, via a three-component one-pot condensation reaction of o-phenylenediamine, aromatic aldehydes and cyclohexyl isocyanide in the presence of perlite–SO3H nanoparticles (diameter/thickness of platelets < 100 nm) underultrasoundirradiation has been demonstrated. The present method offers advantages such
