摘要/Abstract

摘要： 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.
