In the title compound, C19H16O3, an intra­molecular O—H⋯O=C hydrogen bond is formed between the hy­droxy and carbonyl groups on the naphthalene ring system, resulting in an S(6) ring. The angles between the C=O bond vector and the least-squares planes of the naphthalene ring system and the benzene ring are 27.63 (6) and 47.99 (7)°, respectively. The dihedral angle between the latter planes is 61.39 (5)°. In the crystal, two mol­ecules are connected by pairs of inter­molecular O—H⋯O=C hydrogen bonds, forming centrosymmetric dimers with an R22(4) graph-set motif. The mol­ecular packing features C—H⋯π interactions.

In the course of our study on selective peri-aroylation of 2,7-dimethoxynaphthalene (Okamoto & Yonezawa, 2009), the crystal structures of several 1-monoaroylated naphthalene compounds have been clarified along with 1,8-diaroylnaphthalene. Furthermore, selective demethylation reaction of the 1-monoaroylated 2,7-dimethoxynaphthalene compounds has been proved to yield the 1-monoaroyl-2-hydroxynaphthalene compounds, which are rather susceptible to imination reaction. In this course, we recently reported crystal structure of several imine compounds prepared from 1-monoaroylated naphthalene derivatives having 2-hydroxy group exemplified by 1-[(4-chlorophenyl)(phenylimino)methyl]-7-methoxy-2-naphthol-1,4- diazabicyclo[2.2.2]octane (2/1) (Nagasawa et al., 2010a) and 1-[phenyl(3-nitrophenylimino)methyl]-7-methoxy-2-naphthol (Nagasawa et al., 2010c) derived from (4-chlorophenyl)(2-hydroxy-7-methoxynaphthalen-1-yl)methanone (Mitsui et al., 2008) and (2-hydroxy-7-methoxynaphthalen-1-yl)(phenyl)methanone (Nagasawa et al., 2010b), respectively. As a part of our ongoing studies on the synthesis and crystal structure analysis of aroylated naphthalene homologues, we prepared and analysed the crystal structure of the title compound (I).

In the molecule (I), the intramolecular O—H···OC hydrogen bond that forms a six-membered S(6) ring (Etter et al., 1990; Bernstein et al., 1995) including carbonyl and hydroxy groups on the naphthalene ring (Table 1, Fig. 1). The conformation of these groups resembles to that of (2-hydroxy-7-methoxynaphthalen-1-yl)(phenyl)methanone (Nagasawa et al., 2010b). The angles of CO bond vector against the least-squares plane of the naphthalene ring (C1–C10) and benzene ring (C12–C17) are 27.63 (6) and 47.99 (7)°, respectively. The dihedral angle between the naphthalene ring (C1–C10) and benzene ring (C12–C17) is 61.39 (5)°.

In the crystal structure, O—H···OC intermolecular hydrogen bonds between the hydroxy group and the carbonyl one on the naphthalene ring (Table 1) form a centrosymmetric dimer (Fig. 2) with a R22(4) graph set motif (Etter et al., 1990; Bernstein et al., 1995). The molecular packing of (I) is mainly stabilized by intermolecular C—H···π hydrogen bond involving the centroid CT1 of the C5—C10 ring and the centroid CT2 of the C12–C17 phenyl ring. (Table 1).

Experimental top

To a solution of 1-(4-methylbenzoyl)-2,7-dimethoxynaphthalene (3.07 g, 10 mmol) in CH2Cl2 (100 ml) was added AlCl3 (6.65 g, 50 mmol). The reaction mixture was refluxed for 30 min giving a dark red solution, which was then poured into H2O (30 ml). The aqueous layer was extracted with CHCl3 (30 ml × 3). The combined organic layers were washed with brine (30 ml × 3) and dried over MgSO4 overnight. The solvent was removed in vacuo and the crude material was purified by recrystallization from hexane to give compound (I) as yellow platelets (m.p. 385.5–386.00 K, yield 1.76 g, 60%).

Refinement top

All the H-atoms could be located in difference Fourier maps. The coordinates of the OH hydrogen atom were refined using restraint (O1—H1 = 0.95 (2) Å) with Uiso(H) = 1.5Ueq(O). The H atoms attached to carbon were introduced in calculated positions and treated as riding on their parent atoms with C—H= 0.98 Å (methyl) or 0.95 Å (aromatic) with Uiso(H) = 1.2Ueq(Caromatic) or Uiso(H) = 1.5Ueq(Cmethyl).

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