(E)-2-(3,5-Dimethoxybenzylidene)indan-1-one
The title chalcone, C(18)H(16)O(3), was prepared by a solventless base-promoted Claisen–Schmidt condensation and, upon recrystallization from ethanol, obtained in 56% yield. The dihedral angle between the indanone ring system and the benzene ring is 2.54 (4) ° and the C atoms of the methoxy groups d...

| Sumario: | The title chalcone, C(18)H(16)O(3), was prepared by a solventless base-promoted Claisen–Schmidt condensation and, upon recrystallization from ethanol, obtained in 56% yield. The dihedral angle between the indanone ring system and the benzene ring is 2.54 (4) ° and the C atoms of the methoxy groups deviate from the benzene ring by 0.087 (1) and 0.114 (1) Å. In the crystal, π-stacking is the predominant intermolecular force, with the molecules stacking into columns running parallel to the b axis of the unit cell. [Image: see text] |
