Silica sulfuric acid as an efficient and reusable reagent for crossed-aldol condensation of ketones with aromatic aldehydes under solvent-free conditions
Journal of the Brazilian Chemical Society Vol. 15, No. 5, 773–776
چکیده
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.
