(Received 30 September 2010; accepted 7 October 2010; online 13 October 2010)

In the title compound, C19H15BrO3, the dihedral angle between the naphthalene ring system and the benzene ring is 62.51 (8)°. The bridging carbonyl C—C(=O)—C plane makes dihedral angles of 47.07 (6)° with the naphthalene ring system and 24.20 (10)° with the benzene ring. A weak inter­molecular C—H⋯O hydrogen bond exists between the H atom of one meth­oxy group and the O atom of the other meth­oxy group in an adjacent mol­ecule. The crystal packing is additionally stabilized by two types of weak inter­molecular inter­actions involving the Br atom, C—H⋯Br and Br⋯O [3.2802 (14) Å].

Comment top

In the course of our study on selective electrophilic aromatic aroylation of 2,7-dimethoxynaphthalene, peri-aroylnaphthalene compounds have proved to be formed regioselectively with the aid of suitable acidic mediator (Okamoto & Yonezawa, 2009). Recently, we reported the structures of 1,8-diaroyl-2,7-dimethoxynaphthalenes, i. e., 1,8-bis(4-methylbenzoyl)-2,7-dimethoxynaphthalene (Muto et al., 2010), bis(4-bromophenyl)(2,7-dimethoxynaphthalene-1,8-diyl)dimethanone (Watanabe et al., 2010a), and 1-aroyl-2,7-dimethoxynaphthalene, i. e., 1-benzoyl-2,7-dimethoxynaphthalene (Kato et al., 2010). The aroyl groups at the 1,8-positions of the naphthalene rings in these compounds are twistedly bonded in a perpendicular manner but the benzene ring moieties of the aroyl groups tilt slightly toward the exo sides of the naphthalene rings. 1-Aroyl homologues also revealed essentially the same non-coplanar structure as observed for 1,8-diaroylated naphthalenes.

Furthermore, we also reported the crystal structure analysis of the corresponding β-isomers of 3-aroyl-2,7-dimethoxynaphthalenes such as 2-(4-chlorobenzoyl)-3,6-dimethoxynaphthalene (Nakaema et al., 2008) and (3,6-dimethoxy-2-naphthyl)(4-fluorophenyl)methanone (Watanabe et al., 2010b). In these 3-aroylated naphthalenes, which are generally regarded to be thermodynamically more stable than the corresponding 1-positioned isomeric molecules, the aroyl groups are shown connected to the naphthalene rings in a moderately twisted fashion. As part of our ongoing study on these homologous molecules, the synthesis and crystal structure of the title compound, a 3-monoaroylnaphthalene bearing a bromo group, is discussed in this article. The title compound was prepared by a direct condensation reaction of 2,7-dimethoxynaphthalene with 4-bromobenzoic acid.

The molecular structure of the title molecule is displayed in Fig. 1. The 4-bromophenyl group is bonded twistedly away from the attached naphthalene ring. The dihedral angle between the best planes of the bromophenyl ring (C12—C17) and the naphthalene ring (C1—C10) is 62.51 (8)°. The bridging carbonyl plane (O3—C6—C11—C12) makes a relatively large dihedral angle of 47.07 (9)° with the naphthalene ring (C1—C10) [C5—C6—C11—O3 torsion angle = 46.0 (2)°], whereas it makes a rather small angle of 24.20 (10)° with 4-bromophenyl ring (C12—C17) [O3—C11—C12—C17 torsion angle = 24.1 (3)°].

In the crystal structure, the molecular packing of the title compound is stabilized mainly by van der Waals interactions. Moreover, there is a C—H···O hydrogen bond between a hydrogen of the 2-methoxy group, which is situated adjacent to the bromophenyl group, and the ethereal oxygen atom of the 7-methoxy group in the neighboring molecule (Table 1, Fig. 2).

The crystal packing is additionally stabilized by two types of weak intermolecular interactions with the bromine atom: Br1···O3i = 3.2802 (14) Å, and Br1···H5ii = 2.98 Å [symmetry operations: (i) x, y, z + 1, (ii) -x, -y, -z] (Fig. 3) .

Experimental top

The title compound was prepared by treatment of a mixture of 2,7-dimethoxynaphthalene (1.88 g, 10 mmol) and 4-bromobenzoic acid (2.02 g, 10 mmol) with phosphorus pentoxide–methanesulfonic acid mixture (P2O5–MsOH [1/10 w/w]; 10 mL). After the reaction mixture was stirred at 353 K for 8 hours, the mixture was poured into ice-cooled water and extracted with CHCl3 (10 ml × 3). The combined extracts were washed with 2 M aqueous NaOH followed by washing with brine. The organic layer thus obtained was dried over anhydrous MgSO4. The solvent was removed under reduced pressure to give a cake (yield 3.07 g, 83%). The crude product was purified by flush silica gel chromatography (CHCl3). Colorless platelet single crystals suitable for X-ray diffraction were obtained by crystallization from ethanol and chloroform.

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.
