摘要
A new heterogeneous catalyst, nanodiatomite@melamine-SO3H, was introduced for synthesizing 1,8-dioxo-octahydroxanthenes via multicomponent reactions of aldehydes and dimedone. The prepared catalyst was characterized by employing several techniques, including FT-IR, XRD, TGA, EDX, BET, SEM, and TEM. The products were obtained under solvent-free conditions, with high yields in short reaction times. The nanodiatomite@melamine-SO3H was reused five times without substantial activity loss.
