(Received 21 November 2011; accepted 28 November 2011; online 30 November 2011)

In the title compound, C18H15FO4S, the fluoro­benzene ring makes a dihedral angle of 4.3 (1)° with the mean plane of the benzofuran fragment. In the crystal, mol­ecules are linked by weak inter­molecular C—H⋯O hydrogen bonds. The O atom of the sulfinyl group is disordered over two orientations, with site-occupancy factors of 0.940 (3) and 0.060 (3).

Comment top

Recently, substituted benzofuran derivatives have drawn much attention due to their valuable pharmacological properties such as antibacterial and antifungal, antitumor and antiviral, and antimicrobial activities (Aslam et al., 2009, Galal et al., 2009, Khan et al., 2005). These benzofuran derivatives occur in a wide range of natural products (Akgul & Anil, 2003; Soekamto et al., 2003). As a part of our ongoing study of 5,6-(methylenedioxy)benzofuran derivatives containing either 3-methylsulfinyl (Choi et al., 2010a) or 3-ethylsulfinyl (Choi et al., 2010b) substituents, we report herein the crystal structure of the title compound.

In the title molecule (Fig. 1), the benzofuran unit is essentially planar, with a mean deviation of 0.006 (1) Å from the least-squares plane defined by the nine constituent atoms. The dihedral angle formed by the 4-fluorophenyl ring and the mean plane of the benzofuran fragment is 4.3 (1)°. The O atom of the sulfinyl group is disordered over two positions with site-occupancy factors, from refinement, of 0.940 (3) (Part A) and 0.060 (3) (part B). The crystal packing is stabilized by weak intermolecular C—H···O hydrogen bonds; the first one between a methylene H atom and the O atom of the SO unit (Table 1, first entry & Fig. 2), and the second one between a methyl H atom of the isopropyl group and the O atom of the SO unit (Table 1, second entry & Fig. 2).

Experimental top

77% 3-chloroperoxybenzoic acid (224 mg, 1.0 mmol) was added in small portions to a stirred solution of 2-(4-fluorophenyl)-3-isopropylsulfanyl-5,6-methylenedioxy-1-benzofuran (251 mg, 0.8 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 at reduced pressure. The residue was purified by column chromatography (hexane–ethyl acetate, 1:2 v/v) to afford the title compound as a colorless solid [yield 71%, m.p. 437–438 K; Rf = 0.55 (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 ethyl acetate at room temperature.

Refinement top

All H atoms were positioned geometrically and refined using a riding model, with C—H = 0.95 Å for the aryl, 1.00 Å for the methine, 0.99 Å for the methylene, and 0.98 Å for the methyl H atoms. Uiso(H) =1.2Ueq(C) for the aryl, methine, and methylene H atoms, and 1.5Ueq(C) for the methyl H atoms. The O atom of sulfinyl group is disordered over two positions with site-ccupancy factors, from refinement of 0.940 (3) (part A) and 0.060 (3) (part B). The distance of S—O sets was restrained to 0.001 Å using command SADI and DELU.

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.
