What is Dibenzylideneacetone?
Dibenzylideneacetone is an organic compound with the molecular formula C15H14O. This particular compound, dibenzylideneacetone, has two large bent benzylidene groups (C6H5-CH=) bonded to a central acetone. It is defined as a molecule that contains an extended π-system, or most commonly, it consists a series of alternating single and double bonds.
It appears as a pale-yellow crystalline solid with an aromatic smell. It is widely applied in synthetic chemistry, from the preparation of coordination complexes to being an intermediate for organic reactions. Dibenzylideneacetone has also ingested the name dibenzalacetone based off of its general name as it has two benzylidene groups and tweedles,@BIB.C speaker2824, 81.00%
Structure and Properties
The structure of dibenzylideneacetone inhibits a conjugated diene system where the carbon-carbon double bonds alternate with single bonds in such a way as to give rise to non localized electrons. This conjugation makes it chemically reactive and able to absorb light in the ultraviolet (UV) range. Consequently, dibenzylideneacetone has high UV-absorbance and fluorescence properties, which have applications in optics.
These are some important physical properties of dibenzylideneacetone:
Color: Yellow crystalline solid
Solubility: sparingly soluble in water; dissolves well in organc solvent (ethanol, acetone chloroform)
M.p. ~ 104–106 °C.
Boiling point: Around 425°C.
Preparation of Dibenzylideneacetone
Dibenzylideneacetone → the aldol condensation of acetone and benzaldehyde This transformation is catalyzed by an acid or a base. The enolate ion formed from acetone under these conditions reacts with the carbonyl group of a benzaldehyde to form an intermediate, which subsequently dehydrates to give dibenzylideneacetone.
The general sense was something like:
Aldol Condensation Benzaldehyde + Acetone Đ Dibenzylideneacetone + Water
This is classic example of an aldol condensation reaction, which has a long history of application in the construction of carbon-carbon bonds and conjugated systems as exemplified by dibenzylideneacetone.
