Perchloric acid-catalyzed additions of various β-dicarbonyl compounds to a series of secondary alcohols and alkenes could be conveniently conducted in commercial solvent and gave good yields. Moreover, silica gel-supported HClO4 could also catalyze the heterogeneous addition for a series of substrates with similar or even higher yields. The supported catalyst could be readily recovered and reused for four runs.
