The title compound, C30H26O4, contains an oxo-cyclo-hexane ring in a distorted half-chair configuration, with disorder of two C atoms in a 0.859 (4):0.141 (4) ratio. The dihedral angle between the mean planes of the two napthalene ring systems is 58.6 (8)°.
Luminescence is now well established as a sensitive and selective technique for trace analysis of environmental samples.1 In pharmaceutical analysis, however, its frequency of use is reduced. This may be a result of the current ascendancy of high-performance liquid chromatography (HPLC) and the broad band width, featureless luminescence spectra of drug components. In addition, for formulated ph...
The title compound, C(24)H(22)O(4)S, was prepared by reaction between (2E)-3-(6-meth-oxy-2-naphth-yl)-1-(2-thien-yl)prop-2-en-1-one and ethyl acetoacetate. In the crystal, the cyclo-hexenone ring shows a distorted half-chair conformation. The length of the double bond in the cyclohexenone ring [1.343 (4) Å] is normal.
