Yttrium(III) nitrate hexahydrate [Y(NO 3 ) 3 .6H 2 O] as a catalyst for organic reaction is described for the first time. The catalytic activity is demonstrated using Biginelli reaction as a model under solvent-free conditions. Excellent yields of dihydropyrmidinones are obtained at 70 โ€ข C within a
