(Received 27 March 2009; accepted 4 April 2009; online 10 April 2009)

In the title compound, C13H12BrClO4S, the O atom and the methyl group of the methyl­sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. There is a mean deviation of 0.016 (4) Å from the least-squares plane defined by the nine constituent benzofuran atoms. The crystal structure is stabilized by aromatic π–π inter­actions between the benzene rings of neighbouring mol­ecules [centroid–centroid distance = 3.689 (7) Å]and by a weak C—H⋯π interaction between an H atom of the methylene group bonded to the carboxylate O atom and the benzene ring of an adjacent molecule. In addition, the crystal structure exhibits weak non-classical inter­molecular C—H⋯O hydrogen bonds. The chloro­ethyl group is disordered over two positions, with refined site-occupancy factors of 0.767 (6) and 0.233 (6).

Comment top

This work is related to our previous communications on the synthesis and structure of alkyl 2-(5-bromo-3-methylsulfinyl-1-benzofuran-2-yl)acetate analogues, viz. isopropyl 2-(5-bromo-3-methylsulfinyl-1-benzofuran-2-yl)acetate (Choi et al., 2008a) and methyl 2-(5-bromo-3-methylsulfinyl-1-benzofuran-2-yl)acetate (Choi et al., 2008b). Here we report the crystal structure of the title compound, 2-chloroethyl 2-(5-bromo-3-methylsulfinyl-1-benzofuran-2-yl)acetate (Fig. 1).

The benzofuran unit is essentially planar, with a mean deviation of 0.016 (4) Å from the least-squares plane defined by the nine constituent atoms. The chloroethyl group is disordered over two positions with site–occupancy factors of 0.767 (6) (for atoms labelled A) and 0.233 (7) (for atoms labelled B). The molecular packing (Fig. 2) is stabilized by aromatic π–π interactions between the benzene rings of neighbouring molecules, with a Cg···Cgiii distance of 3.689 (7) Å (Cg is the centroid of the C2-C7 benzene ring; symmetry codes as in Fig. 2). The crystal packing is further stabilized by an intermolecular C—H···π interaction between an H atom of the methylene group bonded to the carboxylate O atom and the benzene ring of a neighbouring molecule, with a C11—H11B···Cgi distance of 3.07 Å (Table 1 and Fig. 2; symmetry code as in Fig. 2, Cgi is the centroid of the C2···C7 benzene ring). Additionally, the crystal structure exhibits weak, non-classical, intermolecular C—H···O hydrogen bonds; the first between a benzene H atom and the S═O unit, the second between a benzene H atom and the C═O unit, the third between an H atom of the methylene group bonded to the carboxylate C atom and the furan O atom, and the fourth between an H atom of the methylene group bonded to the carboxylate C atom and the S═O unit, respectively (Table 1 and Fig. 3; symmetry codes as in Fig. 3).

Experimental top

77% 3-Chloroperoxybenzoic acid (271 mg, 1.1 mmol) was added in small portions to a stirred solution of 2-chloroethyl 2-(5-bromo-3-methylsulfanyl-1-benzofuran-2-yl)acetate (380 mg, 1.0 mmol) in dichloromethane (40 ml) at 273 K. After stirring for 3 h at room temperature, the mixture was washed with saturated sodium bicarbonate solution and the organic layer was separated, dried over magnesium sulfate, filtered and concentrated in vacuum. The residue was purified by column chromatography (hexane-ethyl acetate, 1:2 v/v) to afford the title compound as a colorless solid [yield 80%, m.p. 436-437 K; Rf = 0.41 (hexane-ethyl acetate, 1;2 v/v)]. Single crystals suitable for X-ray diffraction were prepared by evaporation of a solution of the title compound in chloroform at room temperature. Spectroscopic analysis: 1H NMR (CDCl3, 400 MHz) δ 3.07 (s, 3H), 3.70 (t, J = 5.48 Hz, 2H), 4.12 (s, 2H), 4.41 (t, J = 5.48 Hz, 2H), 7.41 (d, J = 8.76 Hz, 1H), 7.71 (dd, J = 8.47 Hz and J = 1.82 Hz, 1H), 8.05 (s, 1H).

Refinement top

All H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93 Å for the aryl, 0.97 Å for the methylene, and 0.96 Å for the methyl H atoms.Uiso(H) = 1.2Ueq(C) for the aryl and methylene H atoms, and 1.5Ueq(C) for methyl H atoms. The chloroethyl group is disordered over two positions, with site–occupancy factors, from refinement, of 0.767 (6) (C11A—C12A—ClA) and 0.233 (7) (C11B—C12B—ClB). Both sets of C and Cl atoms were restrained using the commands ISOR (0.01), EADP, and the C—C and C—Cl distances (A & B) were restrained to 1.46 (3) and 1.55 (3) Å, respectively, using the command DFIX. Despite this the atomic displacement parameters for the C atoms of the disordered chhloroethyl group were large, reflecting additional disorder and the room temperature data collection.

Special details top

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 > 2sigma(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.
