In the title compound, C31H20O5, the phenyl rings of the benzoyloxy and benzoyl groups are twisted away from the naphthalene ring system by 64.27 (6), 73.62 (5) and 80.41 (6)°. In the crystal, C—H⋯O hydrogen bonds and C—H⋯π interactions link the molecules, forming tubular chains parallel to the b axis. The chains are further connected into a three-dimensional network by C—H⋯π interactions and π–π stacking contacts [centroid–centroid distances = 3.622 (10)–3.866 (12) Å].

The title compound was prepared via condensation reaction of 1-benzoyl-2,7-dihydroxynaphthalene (0.2 mmol, 52.86 mg) obtained by ethyl ether cleavage reaction of 1-benzoyl-2,7-diethoxynaphthalene, benzoyl chloride (0.4 mmol, 0.046 ml), and triethylamine (0.4 mmol, 0.056 ml) in dichloromethane (2.5 ml). After the reaction mixture was stirred at rt for 2 h, it was poured into water (30 ml) and the mixture was extracted with CHCl3 (10 ml×3). The combined extracts were washed with brine. The organic layers thus obtained were dried over anhydrous MgSO4. The solvent was removed under reduced pressure to give cake. The crude product was purified by recrystallization from ethyl acetate–hexane (3:1 v/v) and colorless single crystals suitable for X-ray diffraction were obtained (isolated yield 36%).

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. |

In the course of our study on electrophilic aromatic aroylation of the naphthalene core, 1,8-diaroylnaphthalene compounds have proved to be formed regioselectively by the aid of a suitable acidic mediator (Okamoto & Yonezawa, 2009, Okamoto et al., 2011). Recently, we have reported the X-ray crystal structures of 1,8-diaroylnaphthalenes, e.g., 1,8-dibenzoyl-2,7-dimethoxynaphthalene (Nakaema et al., 2008). The two aroyl groups at 1,8-positions of the naphthalene ring in these compounds are perpendicularly attached to the naphthalene ring and oriented in opposite directions. Furthermore, we have also clarified the crystal structures of 1-monoaroylated naphthalene compounds such as (2,7-dimethoxynaphthalene-1-yl)-(phenyl)methanone (Kato et al., 2010) and 2,7-dimethoxy-1-(4-nitrobenzoyl)naphthalene (Watanabe et al., 2010). These compounds also exhibit essentially the same non-coplanar structure as the 1,8-diaroylated naphthalenes. Besides, the crystal structures of the aroylnaphthalene derivatives bearing benzoic ester moiety at the 2- or 2,7-positions on the naphthalene ring, 7-methoxy-1-(4-nitrobenzoyl)naphthalene-2-yl 4-nitrobenzoate (Muto et al., 2011) and 1,8-dibenzoylnaphthalene-2,7-diyl dibenzoate (Sakamoto et al., 2012) have been revealed.
The molecular structure of the title compound is displayed in Fig 1. The benzene ring of the benzoyl group is almost orthogonal to the naphthalene ring system forming a dihedral angle of 80.41 (6)° [C10—C1—C11—O1 torsion angle = 83.35 (15)°]. The two carbonyl moieties of the benzoyloxy groups at the 2,7-positions of the naphthalene ring system are in opposite directions relative to one another, as observed in the homologous compound 1,8-dibenzoylnaphthalene-2,7-diyl dibenzoate (Sakamoto et al., 2012). The phenyl ring of the benzoyloxy group at the 7-position is inclined to form a narrower dihedral angle with the naphthalene ring system [64.27 (6)° and O5—C25—C26—C27 torsion angle = -21.8 (2)°] than the phenyl ring of the benzoyloxy group at the 2-position adjacent to the benzoyl group [73.62 (5)° and O3—C18—C19—C24 torsion angle = -2.1 (2)°]. In the crystal, C–H···O hydrogen bonds between an hydrogen atom of the phenyl ring of the benzoyl group and a carbonyl oxygen of the benzoyloxy group and between an hydrogen atom of the naphthalene ring system and a carbonyl oxygen of the benzoyl group, and weak C–H···π interactions (Table 1) link the molecules into tubular chains running parallel to the b axis (Fig. 2 and 3). Furthermore, the chains are connected into a three-dimensional network by weak C–H···π interactions [C15–H15···Cg2 = 2.78 Å; Cg2 is the centroids of the C5–C10 ring] and π–π contacts [Cg2iii···Cg3, 3.622 (10) Å; Cg4···Cg4iv = 3.821 (12) Å; Cg4···Cg4v = 3.866 (12) Å; Cg3 and Cg4 are the centroids of the C1/C4-C9-C10 and C19/C24 rings, respectively; symmetry codes: (iii) 1-x, 1-y, 1-z; (iv) -x, 1-y, 1-z; (v) -x, 2-y, 1-z).
