Solid superbase derived from lanthanum–magnesium composite oxide and its catalytic performance in the knoevenagel condensation under solvent-free condition
We report for the first time the synthesis of a novel solid superbase that was derived from lanthanum-magnesium composite oxide and KOH through thermal treatment. The as-prepared material shows base strength (H-) above 26.5 and is a high-efficiency catalyst for solvent-free Knoevenagel condensation at room temperature. The results of the present study open up a new dimension for the use of composite oxides as new support materials in the synthesis of superbases. © 2011 Elsevier B.V.
