(Received 15 October 2010; accepted 20 October 2010; online 23 October 2010)

In the title compound, C19H15BrO3, the dihedral angle between the naphthalene ring system and the benzene ring is 72.02 (9)°. The bridging carbonyl C—C(=O)—C plane makes dihedral angles of 70.88 (10) and 1.87 (12)°, respectively, with the naphthalene ring system and the benzene ring. In the crystal, two types of weak inter­molecular C—H⋯O inter­actions and a short Br⋯C contact [3.345 (2) Å] are observed.

Comment top

In the course of our study on electrophilic aromatic aroylation of 2,7-dimethoxynaphthalene, peri-aroylnaphthalene compounds have proven to be formed regioselectively with the aid of suitable acidic mediators (Okamoto & Yonezawa, 2009). Recently, we have reported the crystal structures of several 1,8-diaroylated naphthalene homologues exemplified by 1,8-bis(4-methylbenzoyl)-2,7-dimethoxynaphthalene (Muto et al., 2010). The aroyl groups at the 1,8-positions of the naphthalene rings in these compounds are twistedly connected in an almost perpendicular fashion, but the benzene ring moieties of the aroyl groups tilt slightly toward the exo sides of the naphthalene rings. In this course, the crystal structures of 1-monoaroylated naphthalene compounds and the β-isomers of 3-monoaroylated compounds have been also clarified such as 2-(2,7-dimethoxy-1-naphthoyl)benzoic acid (Hijikata et al., 2010), (2,7-dimethoxynaphthalen-1-yl)(phenyl)methanone (Kato, Nagasawa, Hijikata et al., 2010) and (3,6-dimethoxy-2-naphthyl)(4-fluorophenyl)methanone (Watanabe, Muto et al., 2010). The former compounds have revealed to have essentially the same non-coplanar structure with the 1,8-diaroylated naphthalenes. On the other hand, presence of bromo groups in these compounds are shown to demonstrate somewhat different as displayed for aroylated naphthalene homologues bearing bromo group, i.e., bis(4-bromophenyl)(2,7-dimethoxynaphthalene-1,8-diyl)dimethanone (Watanabe, Nakaema et al., 2010) and (4-bromophenyl)(3,6-dimethoxy-2-naphthyl)methanone The 4-bromophenyl group is out of the plane of the naphthalene ring. (Kato, Nagasawa, Kataoka et al., 2010). In the crystal structures, the dihedral angles between naphthalene and bromophenyl rings are demonstrated to have rather small compared to the corresponding without bromo group compounds. As a part of the course of our continuous study on the molecular structures of these kinds of homologous molecules, the crystal structure of title compound, a 1-bromobenzoylated naphthalene derivative, is discussed in this paper.

The molecular structure of the title compound is displayed in Fig. 1. The 4-bromophenyl group is out of the plane of the naphthalene ring. The dihedral angle between the best planes of the bromophenyl ring (C12—C17) and the naphthalene ring (C1—C10) is 72.02 (9)°. The carbonyl group and the 4-bromophenyl group have almost coplanar configuration [O3—C11—C12—C13 torsion angle = 2.5 (3)°]. On the other hand, the carbonyl group makes torsion angle of 70.3 (3)° with the naphthalene ring plane.

In the crystal structure, the molecular packing of the title compound is stabilized mainly by van der Waals interactions. The crystal packing is additionally stabilized by intermolecular C—H···O hydrogen bonding between the oxygen atom (O1) of the 2-methoxy group and one hydrogen atom (H6) of the naphthalene ring of the adjacent molecule along the a axis (C6—H6···O1i; Fig. 2 and Table 1). Moreover, there is also intermolecular C—H···O hydrogen bonding between the oxygen atom (O2) of the 7-methoxy group and one hydrogen atom (H17) of the 4-bromophenyl group of the adjacent molecule along the c axis (C17—H17···O2ii; Fig. 3 and Table 1). Furthermore, an intermolecular interaction between the bromine atom and the naphthalene ring carbon [C8···Br1iii = 3.345 (2) Å; (iii) -x + 1, -y, -z] is observed (Fig. 4).

Experimental top

To a 100 ml flask, 4-bromobenzoyl chloride (11 mmol, 2.403 g), aluminium chloride (13.3 mmol, 1.769 g) and methylene chloride (25 ml) were placed and stirred at 273 K. To the reaction mixture thus obtained, 2,7-dimethoxynaphthalene (9.9 mmol, 1.869 g) and methylene chloride (25 ml) were added. After the reaction mixture was stirred at 273 K for 6 h, it was poured into ice-cold water (10 ml). The aqueous layer was extracted with CHCl3 (10 ml × 3). The combined extracts were washed with 2 M aqueous NaOH followed by washing 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 ethanol (57% yield). Colorless platelet single crystals suitable for X-ray diffraction were obtained by repeated crystallization from ethanol.

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.
