Poly-substituted quinolines were synthesized in the presence of a catalytic amount of dodecylphosphonic acid (DPA) in aqueous media and solvent-free conditions. The reactions proceed very well under relatively mild conditions, and DPA can be recycled.

## Abstract A rapid and an efficient method for the preparation of a variety of substituted quinolines has been developed through the reactions of __o__‐aminoarylketones with carbonyl compounds containing a reactive α‐methylene moiety in the presence of molten [Et~3~NH][HSO~4~] under solvent‐free c
