A convenient synthesis of coumarinyl chalcones using HClO4–SiO2: A green approach
HClO4–SiO2 catalyzed synthesis of coumarinyl chalcones (8a–j) under solvent-free conditions is reported. The catalyst is characterized by powder XRD and SEM–EDX analysis. The stability of the catalyst is evaluated by thermogravimetric (TG) and differential scanning calorimetry (DSC) techniques. The...
