SALEHI, Peyman; DABIRI, Minoo; ZOLFIGOL, Mohammad Ali  y  FARD, Mohammad Ali Bodaghi. Silica sulfuric acid as an efficient and reusable reagent for crossed-aldol condensation of ketones with aromatic aldehydes under solvent-free conditions. J. Braz. Chem. Soc. [online]. 2004, vol.15, n.5, pp.773-776. ISSN 1678-4790.

Aromatic aldehydes undergo crossed-aldol condensation with ketones in the presence of silica sulfuric acid under solvent-free conditions to afford the corresponding a, b-unsaturated aldol products in excellent yields. The reagent is reusable for several times without any decrease in the yield of the reactions.

Palabras clave : crossed-aldol condensation; silica sulfuric acid; solid phase; a, b-unsaturated carbonyls.
