| Dibenzylideneacetone Usage And Synthesis |
| Chemical Properties | trans,trans-Dibenzylideneacetone is a crystalline solid, melting point 110-111℃; cis-trans is a light yellow needle crystal, melting point 60℃; cis-cis is a yellow oily liquid, boiling point 130℃ (2.7Pa). Soluble in ethanol, acetone, chloroform, insoluble in water. | | Uses | Dibenzylideneacetone is used as a ligand to prepare palladium catalysts, which are widely used in catalytic hydrogenation, coupling, carbonylation, alkyne ring trimerization, etc. | | Preparation | 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%. | | Synthesis Reference(s) | Chemistry Letters, 9, p. 51, 1980The Journal of Organic Chemistry, 45, p. 3840, 1980 DOI: 10.1021/jo01307a022Organic Syntheses, Coll. Vol. 2, p. 167, 1943 | | Purification Methods | Crystallise the ketone from hot ethyl acetate (2.5mL/g) or EtOH. [Beilstein 7 IV 1747.] |
