In this work, novel ionic liquid namely sulfonic acid functionalized pyridinium chloride {[Pyridine-SO3H]Cl} is synthesized, and characterized by studying its IR, UV, 1H and 13C NMR as well as mass spectra. This ionic liquid is used as an efficient, homogeneous and reusable catalyst for the solvent-free synthesis of 12-aryl-8,9,10,12- tetrahydrobenzo[a]-xanthen-11-ones by the one-pot multi-component condensation of 2-naphthol with arylaldehydes and dimedone (5,5-dimethylcyclohexane-1,3- dione).
