The modification of natural phosphate (NP) with sodium nitrate by calcination produces an extremely efficient basic catalyst for the Claisen-Schmidt condensation. A large variety of chalcones is easily obtained in high yield at room temperature using only a catalytic amount of NaNO3/NP. (C) 2001 Elsevier Science Ltd. All rights reserved.
