A series of 2,4-disubstituted quinolines were easily prepared through a one-pot reaction of structurally diverse 2-aminoaryl ketones with various arylacetylenes in the presence of K5CoW12O40 • 3 H2O as a reusable and environmentally benign catalyst under microwave irradiation and solvent-free conditions.
