(Received 22 July 2009; accepted 4 August 2009; online 8 August 2009)

In the title compound, C15H10FIO2S, the O atom and the methyl group of the methyl­sulfinyl substituent lie on opposite sides of the plane through the benzofuran fragment. The 4-iodo­phenyl ring is rotated out of the benzofuran plane by a dihedral angle of 39.4 (1)°. The crystal structure is stabilized by an inter­molecular C—H⋯O hydrogen bond and an I⋯O halogen bond [3.055 (2) Å]. The crystal structure also exhibits an inter­molecular C—H⋯π inter­action between the methyl H atom and the 4-iodo­phenyl ring of an adjacent benzofuran mol­ecule, and aromatic π–π inter­actions between the benzene rings of neighbouring benzofuran systems [centroid–centroid distance = 3.558 (3) Å].

Comment top

The benzofuran ring systems have received considerable attention in the field of their biological and pharmacological properties (Howlett et al., 1999; Twyman & Allsop, 1999). This work is related to our communications on the synthesis and structures of 2-(4-iodophenyl)-3-methylsulfinyl-1-benzofuran analogues, viz. 2-(4-iodophenyl)-5-methyl-3-methylsulfinyl-1-benzofuran (Choi et al., 2008a) and 2-(4-iodophenyl)-5,7-dimethyl-3-methylsulfinyl-1-benzofuran (Choi et al., 2008b). Here we report the crystal structure of the title compound (Fig. 1).

The benzofuran unit is essentially planar, with a mean deviation of 0.010 (2) Å from the least-squares plane defined by the nine constituent atoms. The dihedral angle formed by the planes of the benzofuran and the 4-iodophenyl rings is 39.4 (1)°. The crystal packing (Fig. 2) is stabilized by an intermolecular C–H···O hydrogen bond and an I···O halogen bond (Politzer et al., 2007); the first between the methyl H atom and the S═O unit, with a C15–H15C···O2i distance of 3.238 (3) Å (Table 1), the second between the iodine atom and the oxygen of the S═O unit, i.e. an I···O distance of 3.055 (2) Å and a nearly linear C12–I···O2iii angle of 165.26 (8)°. The crystal packing (Fig. 3) also exhibits an intermolecular C–H···π interaction between the methyl H atom and the 4-bromophenyl ring of an adjacent molecule, with a C15–H15B···Cg3ii (Table 1; Cg3 is the centroid of the C9-C14 benzene ring). The further stability comes from aromatic π–π interaction between the furan and the benzene rings of the adjacent molecules, with a Cg1···Cg2iv distance of 3.558 (3) Å (Fig. 3; Cg1 and Cg2 are the centroids of the C1/C2/C7/O2/C8 furan ring and the C2-C7 benzene ring, respectively).

Experimental top

The 77% 3-chloroperoxybenzoic acid (291 mg, 1.3 mmol) was added in small portions to a stirred solution of 5-fluoro-2-(4-iodophenyl)-3-methylsulfanyl-1-benzofuran (310 mg, 1.2 mmol) in dichloromethane (30 mL) at 273 K. After being stirred at room temperature for 3h, 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 (hexan-ethyl acetate, 1 : 2 v/v) to afford the title compound as a colorless solid [yield 81%, m.p. 482-483 K; Rf = 0.71 (hexane-ethyl acetate, 1:2 v/v)]. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of the title compound in tetrahydrofuran at room temperature.

Refinement top

All H atoms were positioned geometrically and refined using a riding model, with C–H = 0.93 Å for aromatic H atoms and 0.96 Å for methyl H atoms, respectively, and with Uiso(H) = 1.2Ueq(C) for aromatic H atoms and 1.5 Ueq(C) for methyl H atoms, respectively.

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.
