Abstract
3-SCF 3 substituted 4-methyl-2(1H)-, 4-phenyl-2(1H)-, 2-methyl-4(1H), and 2-phenyl-4(1H)-quinolinones were obtained by cyclization of the respective -SCF 3 submitted acetoacetanilides or benzoylacetanilides or their β-phenylimino analogues in concentrated sulphuric acid upon heating. The structures of the compounds obtained were elucidated by elemental analysis and their IR, 1H and 19F NMR, and mass spectra.
