In the title compound, C21H14BrFO2S, the dihedral angles between the mean plane [r.m.s. deviation = 0.005 (1) Å] of the benzofuran ring system and the pendant 4-fluorophenyl and phenyl rings are 1.50 (8) and 81.47 (6)°, respectively. In the crystal, molecules are linked by weak C—H⋯O hydrogen bonds into supramolecular chains running along the a-axis direction. A short S⋯O contact [2.9623 (13) Å] involving the sulfinyl groups is observed between inversion-related chains.

3-Chloroperoxybenzoic acid (77%, 202 mg, 0.9 mmol) was added in small portions to a stirred solution of 5-bromo-2-(4-fluorophenyl)-7-methyl-3-phenylsulfanyl-1-benzofuran (330 mg, 0.8 mmol) in dichloromethane (30 mL) at 273 K. After being stirred at room temperature for 5h, 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
(hexane-ethyl acetate, 2:1 v/v) to afford the title compound as a colorless solid [yield 56%, m.p. 485–486 K; Rf = 0.72 (hexane–ethyl acetate, 2:1 v/v)]. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of the title compound in benzene at room temperature.All H atoms were positioned geometrically and refined using a riding model, with C—H = 0.95 for aryl and 0.98 Å for methyl H atoms. Uiso(H) = 1.2Ueq(C) for aryl and 1.5Ueq(C) for methyl H atoms. The positions of methyl hydrogens were optimized rotationally.
As a part of our continuing study of 5-bromo-3-phenylsulfinyl-1-benzofuran derivatives containing phenyl (Choi et al., 2009) and 4-fluorophenyl (Seo et al., 2011) substituents in 2-position, we report herein the
of the title compound.In the title molecule (Fig. 1), the benzofuran unit is essentially planar, with a mean deviation of 0.005 (1) Å from the least-squares plane defined by the nine constituent atoms. The dihedral angles between the mean plane of the benzofuran ring system and the pendant 4-fluorophenyl and phenyl rings are 1.50 (8) and 81.47 (6)°, respectively. In the
(Fig. 2), molecules are connected by weak C—H···O hydrogen bonds (Table 1) into chains extending along the a-axis direction, these chains are further packed into stacks by a sulfinyl–sulfinyl interaction (Choi et al., 2008) interpreted as similar to a type-ll carbonyl–carbonyl interaction (Allen et al., 1998), with a S1···O2ii distance of 2.9623 (13) Å [symmetry code: (ii) 1- x, - y, 1- z].For background information and the crystal structures of related compounds, see: Choi et al.

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. |

As a part of our continuing study of 5-bromo-3-phenylsulfinyl-1-benzofuran derivatives containing phenyl (Choi et al., 2009) and 4-fluorophenyl (Seo et al., 2011) substituents in 2-position, 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 0.005 (1) Å from the least-squares plane defined by the nine constituent atoms. The dihedral angles between the mean plane of the benzofuran ring system and the pendant 4-fluorophenyl and phenyl rings are 1.50 (8) and 81.47 (6)°, respectively. In the crystal structure (Fig. 2), molecules are connected by weak C—H···O hydrogen bonds (Table 1) into chains extending along the a-axis direction, these chains are further packed into stacks by a sulfinyl–sulfinyl interaction (Choi et al., 2008) interpreted as similar to a type-ll carbonyl–carbonyl interaction (Allen et al., 1998), with a S1···O2ii distance of 2.9623 (13) Å [symmetry code: (ii) 1- x, - y, 1- z].
