The reactions were carried out in 1,2-dichloroethane at room temperature or under solvent-free media at elevated temperature. The present methodology offers several advantages such as excellent yields, simple procedure and the catalyst exhibited remarkable reusability.

The present procedure offers advantages such as shorter reaction time (<2 h), simple workup, excellent yields, recovery and reusability of catalyst.

In aqueous medium both HClO4–SiO2 and PPA–SiO2 catalysts yielded only 4 as the product. The scope and limitations of the two catalysts in various reaction conditions examined were described.
