用途有機合成原料。
使用Dibenzylideneacetone is used as a ligand to prepare palladium catalysts, which are widely used in catalytic hydrogenation, coupling, carbonylation, alkyne ring trimerization, etc.
製造方法Dibenzylideneacetone is obtained by the reaction of benzaldehyde and acetone. The reaction was carried out in aqueous ethanol solution at a reaction temperature of 20-25°C with a yield of 78%.
純化方法Crystallise the ketone from hot ethyl acetate (2.5mL/g) or EtOH. [Beilstein 7 IV 1747.]
