Abstract: Aromatic aldehydes undergo crossaldol condensation with ketones in the presenc e of carbon-based solid acid under solvent free conditions to afford the correspondingα,β-unsaturated aldol products in excellent yields. The catalyst is reusable several times without any decrease in the yield of the reactions.

Key words: Carbon-based solid acid, ketone, aromatic aldehyde, cross-aldol condensation, solid phase, α, β-unsaturated carbonyl
