In the title compound, C17H13FO4S, the 4-fluoro­phenyl ring makes a dihedral angle of 4.92 (4)° with the plane of the 5,6-methyl­enedi­oxy-1-benzofuran fragment. In the crystal, mol­ecules are linked by weak inter­molecular C—H⋯O and C—H⋯F hydrogen bonds.

Comment top

Compounds involving a benzofuran skeleton show various pharmacological activities such as antifungal (Aslam et al.., 2006), antitumor and antiviral (Galal et al.., 2009), and antimicrobial (Khan et al.., 2005). These compounds occur widely in nature (Akgul & Anil, 2003; Soekamto et al.., 2003). As a part of our ongoing studies of the effect of side chain substituents on the solid state structures of 2-aryl-5,6-methylenedioxy-3-methylsulfinyl-1-benzofuran analogues (Choi et al., 2007, 2010), we report the crystal structure of the title compound (Fig. 1). The structure shows both intermolecular C-H···O and C–H···F hydrogen bonds, whereas aromatic π···π interactions were found in 5,6-methylenedioxy-3-methylsulfinyl-2-phenylbenzofuran (Choi et al., 2007) and only intermolecular C–H···O hydrogen bonds were observed in 2-(4-fluorophenyl)-5,6-methylenedioxy-3-methylsulfinyl-1-benzofuran (Choi et al., 2010).

The 5,6-(methylenedioxy)benzofuran unit is essentially planar, with a mean deviation of 0.013 (1) Å from the least-squares plane defined by the twelve constituent atoms. The dihedral angle formed by this plane and the 4-fluorophenyl ring is 4.92 (4)°. The molecular packing (Fig. 2) is stabilized by intermolecular C–H···O hydrogen bonds; the first one between the 4-fluorophenyl H atom and the oxygen of the SO unit, with a C12–H12···O4i, the second one between the methyl H atom of ethyl group and the oxygen of the SO unit, with a C17–H17B···O4iii, respectively (Table 1). The crystal packing (Fig. 2) is further stabilized by intermolecular C–H···F hydrogen bonds between the methylene H atom of ethyl group and the fluorine, with a C16–H16A···Fii (Table 1).

Experimental top

77% 3-Chloroperoxybenzoic acid (202 mg, 0.9 mmol) was added in small portions to a stirred solution of 3-ethylsulfanyl-2-(4-fluorophenyl)-5,6-methylenedioxy-1-benzofuran (253 mg, 0.8 mmol) in dichloromethane (30 mL) at 273 K. After being stirred at room temperature for 4h, 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 (silica gel, ethyl acetate) to afford the title compound as a colorless solid [yield 79%, m.p. 449-450 K; Rf = 0.61 (ethyl acetate)]. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of the title compound in chloroform at room temperature.

Refinement top

All H atoms were positioned geometrically and refined using a riding model, with C–H = 0.93 Å for aryl, 0.97 Å for methylene, and 0.96 Å for methyl H atoms. Uiso(H) = 1.2Ueq(C) for aryl and methylene H atoms, and 1.5Ueq(C) for methyl H atoms.

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.
