Abstract
The title compound, C22H20O, was synthesized by reacting 4-
isopropylbenzaldehyde with 2-acetonaphtone by aldolic
condensation under Claisen–Schmidt conditions. The molecule consists of a naphthalene group and a benzene ring with
a pendant isopropyl moiety, both rings bound by a propenone
linker. The naphthalene ring system is almost planar
[maximum deviation from the least-squares plane =
0.026 (10) A˚ ] and subtends a dihedral angle of 52.31 (4) with
the benzene ring. The propenone linker, in turn, deviates
slightly more from planarity [maximum deviation =
0.125 (18) A˚ ] and has its least-squares plane oriented midway
the former two, at 25.62 (6) and 28.02 (5) from the
naphthalene ring system and the benzene ring, respectively.
Finally, the isopropyl group presents its CC2 plane almost
perpendicular to the benzene ring, at 85.30 (4) . No significant
hydrogen bonding or – stacking interactions are found in
the crystal structure
