Description:
Ruthenium supported on surface modified magnetic nanoparticles (NiFe2O4) has been successfully synthesized and applied for hydrogenation of alkynes at room temperature as well as transfer hydrogenation of a number of carbonyl compounds under microwave irradiation conditions. The catalyst shows excellent selectivity towards the desired products with high yield even after 5 repeated cycles. In case of transfer hydrogenation reactions, microwave irradiation has reduced the time period from several hours to a few minutes. The ease of separation, high activity and selectivity aspects of this catalyst will be highlighted.
