Abstract top

In the title compound, C26H22Cl2O4, the cyclohexenone ring adopts an approximate half-chair conformation, with two C atoms displaced by -0.485 (6) and 0.218 (6) Å from the plane of the other four ring atoms. The dihedral angles between its four almost coplanar [maximum deviation = 0.006 (2) Å] atoms and the benzene and naphthalene ring systems are 59.26 (13) and 79.94 (9)°, respectively. The dihedral angle between the aromatic rings systems is 77.14 (7)°. A short intramolecular C-H...Cl contact generates an S(6) ring. In the crystal, molecules are linked by C-H...O and C-H...Cl interactions to generate a three-dimensional network.

Comment top

The structure of the title compound, (I), (Fig. 1), was determined as part of our ongoing structural studies (Li et al., 2009a,b) of substituted cyclohexenones.

The cyclohexenone ring (C7–C12) in (I) adopts an approximate half-chair conformation with C7/C8/C11/C12 statistically coplanar [r.m.s. deviation = 0.0004 Å; individual deviations = 0.0006 (19), -0.0003 (9), 0.0003 (9) and -0.006 (2) Å, respectively] and C9 and C10 displaced from their mean plane by -0.485 (6) and 0.218 (6) Å, respectively. Unlike the equivalent atoms in the related structures ethyl 6-(6-methoxy-2-naphthyl)-4-(4-methylphenyl)-2-oxocyclohex-3- ene-1-carboxylate, (II), (Li et al., 2009a) and ethyl 6-(6-methoxy-2-naphthyl)-2-oxo-4-(2-thienyl)cyclohex-3- ene-1-carboxylate, (III), (Li et al., 2009b), C9 and C10 in (I) do not display positional disorder. Both atoms are stereogenic centres: in the arbitrarily chosen asymmetric molecule, C9 has R configuration and C10 has S, but crystal symmetry generates a racemic mixture of enantiomers.

The dihedral angles between C7/C8/C11/C12 and the benzene (C1–C6) and naphthalene (C13–C22) ring systems are 59.26 (13) and 79.94 (9)°, respectively. The dihedral angle between the aromatic rings systems in (I) is 77.14 (7)°: equivalent values in (II) and (III) are 73.10 (5) and 86.04 (16)°, respectively. The naphthalene ring system (atoms C13–C22) in (I) shows rather high deviations from planarity: the r.m.s. deviation is 0.044Å and maximum deviations are 0.074 (2)Å for C13 and -0.055 (2) for C21. If the two benzene rings (C13/C14/C15/C16/C21/C22 and C16–C21) are considered separately, their r.m.s. deviations are 0.018 and 0.007 Å, respectively, and the dihedral angle between them is 4.85 (16)°. Atom C23 of the terminal methyl group is displaced from the naphthalene ring by 0.466 (4) Å. A short intramolecular C8—H8B···Cl2 contact (Table 1) generates an S(6) ring.

In the crystal, the molecules are linked by C—H···O and C—H···Cl interactions to generate a three-dimensional network.

Experimental top

(2E)-1-(2,4-Dichlorophenyl)-3-(6-methoxy-2-naphthyl)prop-2-en-1-one (1.8 g, 5 mmol) and ethyl acetoacetate (0.65 g, 5 mmol) were refluxed for 4 hr in 15 ml of ethanol in the presence of 0.8 ml 10% NaOH. The mixture was cooled to room temperature and the reaction mass was filtered and recrystallized using acetonitrile to yield colourless blocks of (I) (m.p.: 393–395 K).

Refinement top

The hydrogen atoms were geometrically placed (C—H = 0.95–1.00 Å) and refined as riding with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C). A rotating rigid-group model was applied to the methyl group.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
