| Popis: | The title compound, C17H13ClO2, was obtained from the oxidation of 6-chloro-4-(2-phenylethenyl)chroman-2-ol, which was synthesized by the reaction of of (E)-3-(5-chloro-2-hydroxyphenyl)acrylaldehyde with styrylboronic acid using diethylamine as a catalyst. The six-membered pyranone ring of the chromane system has a screw-boat conformation. The dihedral angle between the least-squares planes of the chromane ring system and the styryl group is 85.28 (9)°. |
