摘要
Silica supported perchloric acid (HClO4 center dot SiO2) has been utilized as a heterogeneous recyclable catalyst for a highly efficient and chemo- and stereoselective conversion of beta-dicarbonyl compounds by treatment with amines at room temperature into beta-enaminones and beta-enamino esters under solvent-free conditions.
