The title mol­ecule, C30H28O6, possesses crystallographically imposed twofold symmetry, with two central C atoms in the naphthalene unit lying on the rotation axis along [001]. The 4-eth­oxy­benzoyl groups at the peri positions of the naphthalene ring system are disordered over two sets of sites with occupancies of 0.769 (4) and 0.231 (4). They are directed in opposite directions from the naphthalene plane (anti orientation). For the major component, the dihedral angle between the aroyl benzene ring and the naphthalene ring system is 75.62 (13)° [minor component 75.5 (4)°], and that between the aroyl benzene rings is 32.58 (15)°. In the crystal, mol­ecules are linked via C—H⋯O and C—H⋯π inter­actions, forming a three-dimensional network.

Comment top

In the course of our study on selective electrophilic aromatic aroylation of the naphthalene ring 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-diaroylated 2,7-dimethoxynaphthalene derivatives such as 1,8-bis(4-butoxylbenzoyl)-2,7-dimethoxynaphthalene [{8-[4-(butoxy)benzoyl]-2,7-dimethoxynaphthalen-1-yl}[4-(butoxy)phenyl]methanone] (Sasagawa et al., 2011), 1,8-bis(4-methoxybenzoyl)-2,7-dimethoxynaphthalene [{2,7-dimethoxy-8-(4-methoxybenzoyl)-naphthalen-1-yl}(4-methoxyphenyl)-methanone chloroform monosolvate] (Sasagawa, Sakamoto et al., 2013) and 1,8-bis(4-isobutylbenzoyl)-2,7-dimethoxynaphthalene [{2,7-dimethoxy-8-[4-(2-methylpropyl)benzoyl]-naphthalen-1-yl}{4-(2-methylpropyl)phenyl-methanone}] (Sasagawa et al., 2012).

The aroyl groups in these compounds are almost perpendicularly attached to the naphthalene rings and oriented in opposite directions (anti-orientation). According to the authors' knowledge, most 1,8-diaroylnaphthalene derivatives have anti-oriented structures. Recently, we have also clarified another structure of the 1,8-diaroylnaphthalene derivatives, where the two aroyl groups are situated in same direction (syn-orientation), 2,7-dimethoxy-1,8-bis(4-phenoxybenzoyl)naphthalene (Hijikata et al., 2010) and 1,8-bis(4-isopropoxybenzoyl)-2,7-dimethoxynaphthalene [{2,7-dimethoxy-8-[4-(propan-2-yloxy)-benzoyl]naphthalen-1-yl}[4-(propan-2-yloxy)phenyl]methanone] (Sasagawa, Takeuchi et al., 2013). As a part of our ongoing studies on the molecular structures of these kinds of homologous molecules, the X-ray crystal structure of the title compound, 1,8-diaroylated naphthalene bearing ethoxy groups on the aroyl moieties, is discussed herein.

The molecular structure of the title compound is displayed in Fig 1. The title molecule lies on a crystallographic twofold axis so that the asymmetric unit contains one-half of the molecule. Thus, two 4-ethoxybenzoyl groups are situated in anti-orientation and are twisted away from the attached naphthalene ring. The dihedral angle between the best planes of the 4-ethoxyphenyl groups and the naphthalene ring system is 75.62 (13)° [or 75.5 (4)° for minor position].

The torsion angles along the bond between the naphthalene ring system and the bridging carbonyl moiety, C2—C1—C7—O1, is -109.85 (12)° , whereas that between the phenyl group and the bridging carbonyl moiety (O1—C7—C8—C9) is -169.0 (4)°.

In the crystal, C—H···O and two kinds of C—H···π interactions link the molecules and form a three-dimensional network (Table 1, Fig 2; symmetry code: -x + 1, y + 1/4, z + 1/4): a C—H···O interaction between a hydrogen atom of the methyl moiety in the ethoxy group and the oxygen atom of the carbonyl moiety (C16—H16···O1 = 2.51 Å), a C—H···π interaction between a hydrogen atom of the methoxy group and the π-system of benzene ring (C14—H14C···Cg1 = 2.83 Å; Cg1 is the centroid of C8-C13 ring), and a C—H···π interactions between a hydrogen atom of the methylene moiety in the ethoxy group and the π-system of naphthalene ring (C15—H15B···Cg2 = 2.80 Å; Cg2 is the centroid of C1-C6 ring).

Experimental top

The title compound was prepared by SN2 reaction of 1,8-bis(4-hydroxybenzoyl)-2,7-dimethoxynaphthalene (2.0 mmol, 857 mg), which was obtained via SNAr reaction of 1,8-bis(4-fluorobenzoyl)-2,7-dimethoxynaphthalene with sodium hydroxide, with ethyl iodide (6.0 mmol, 936 mg) and potassium carbonate (5.6 mmol, 774 mg) in N,N-dimethylformamide (DMF; 5.0 ml). After the reaction mixture was stirred at 328 K for 6 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 (93% yield). The crude product was purified by recrystallization from ethyl acetate (isolated yield 56%). Furthermore, the isolated product was crystallized from ethyl acetate to give single crystal. (m.p. = 473.6—477.6 K). Spectroscopic data for the title compound is available in the archived CIF.

Refinement top

All H atoms were found in a difference map and were subsequently refined as riding atoms, with C—H = 0.95 (aromatic), 0.98 (methyl) and 0.99 (methylene) Å with Uĩso(H) = 1.2Ueq(C) or 1.5 Ueq(C). The 4-ethoxybenzene group is disordered over two positions with atoms C7/C7' and C16/C16' completely overlapping. The coordinates and anisotropic displacement parameters of these atomic pairs were constrained with EXYZ and EADP instructions of SHELXL-97 (Sheldrick, 2008). Moreover restraints were imposed on the geometry of the minor orientation with the instruction SAME. The occupancies of the two postions refined at 0.769 (4) and 0.231 (4).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
