摘要：

Activated Fly ash, an industrial waste (pollutant) is found to be well suited for catalyzing reactions which are having industrial, pharmacological and therapeutic importance, e. g. Knoevenagel condensation, 'One-Pot' conversions of ketones to amides, via, Beckmann rearrangement, Schiff Bases formation, Biginelli and Hantzsch reactions under microwave irradiation in solvent-free conditions. Moreover, this catalyst shows a promising future in that it can provide environmentally clean processes for the chemical industry.
