Zinc chloride (273 mg, 2.0 mmol) was added to a stirred solution of 4-fluoro-4'-hydroxybiphenyl (376 mg, 2.0 mmol) and 2-chloro-2-methylsulfanylacetophenone (401 mg, 2.0 mmol) in dichloromethane (30 mL) at room temperature, and stirring was continued at the same temperature for 1 h. The reaction was quenched by the addition of water and the organic layer was separated, dried over magnesium sulfate, filtered and concentrated at reduced pressure. The residue was purified by
(hexane–benzene, 5:2 v/v) to afford the title compound as a colorless solid [yield 61%, m.p. 415–416 K; Rf = 0.78 (hexane–benzene, 5:2 v/v)]. Colourless blocks were prepared by slow evaporation of a solution of the title compound in carbon tetrachloride at room temperature.The reported
was obtained by TWIN/BASF procedure in SHELXL (Sheldrick, 2008). All H atoms were positioned geometrically and refined using a riding model, with C—H = 0.95 Å 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.Recently, many compounds having a benzofuran moiety 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 studies of the substituent effect on the solid state structures of 2-(4-halophenyl)-3-methylsulfanyl-5-phenyl-1-benzofuran analogues (Choi et al., 2009, 2010), we report herein the
of the title compound.The title compound crystallizes as the non-centrosymmetric
P21 in spite of having no asymmetric C atoms. The crystal studied was an with a 0.68 (9) : 0.32 (9) domain ratio.In the title molecule (Fig. 1), the benzofuran unit is essentially planar, with a mean deviation of 0.006 (2) 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 benzofurn fragment is 31.72 (6)°. The dihedral angle between the phenyl ring and the mean plane of the benzofurn fragment is 32.51 (6)°. The crystal packing (Fig. 2) is stabilized by intermolecular C—H···π interactions between a 4-fluorophenyl H atom and the phenyl ring (Table 1; C14—H14···Cgi, Cg is the centroid of the C15–C20 phenyl ring).

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. |

Recently, many compounds having a benzofuran moiety 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 studies of the substituent effect on the solid state structures of 2-(4-halophenyl)-3-methylsulfanyl-5-phenyl-1-benzofuran analogues (Choi et al., 2009, 2010), we report herein the crystal structure of the title compound.
The title compound crystallizes as the non-centrosymmetric space group P21 in spite of having no asymmetric C atoms. The crystal studied was an inversion twin with a 0.68 (9) : 0.32 (9) domain ratio.
In the title molecule (Fig. 1), the benzofuran unit is essentially planar, with a mean deviation of 0.006 (2) 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 benzofurn fragment is 31.72 (6)°. The dihedral angle between the phenyl ring and the mean plane of the benzofurn fragment is 32.51 (6)°. The crystal packing (Fig. 2) is stabilized by intermolecular C—H···π interactions between a 4-fluorophenyl H atom and the phenyl ring (Table 1; C14—H14···Cgi, Cg is the centroid of the C15–C20 phenyl ring).
