Abstract:A green and robust solid base MgO has been synthesized by a rapid microwave-assisted solution combustion
synthesis method and evaluated for multicomponent Mannich reaction under solvent-free conditions at ambient temperature
in the liquid phase. The synthesized catalyst was characterized by various techniques to ascertain its phase composition
and thermal stability. Catalyst characterization studies revealed that magnesium oxide synthesized by microwaveassisted
solution combustion synthesis method offers stable nanosized MgO crystallites. Good to excellent yields of β-amino carbonyl compounds were achieved with aromatic aldehydes bearing an electron withdrawing group.
