| Abstract: | Aromatic aldehydes underwent cross-aldol condensation with ketones in the presence of acti-vated carbon supported sulfuric acid (acsa) under solvent-free conditions to afford 16 corresponding α/β-unsaturated aldol products in reaction time of 30～100 min, and the good yields from 65% to 94%. This method provides a simple, fast and clean reaction, using a small quantity of catalyst and a simple workup procedure. The catalyst could be reused. The structures of the products were characterized by IR, ~1H NMR and ~(13)C NMR techniques. |
