Comment
=======

As a part of our ongoing studies on the synthesis and structure of 2-aryl-3-methylsulfinyl-1-benzofuran analogues, the crystal structure of 2-(4-bromophenyl)-5-methyl-3-methylsulfinyl-1-benzofuran (Choi *et al.*, 2007*a*) and 2-(4-bromophenyl)-5,7-dimethyl-3-methylsulfinyl-1-benzofuran (Choi *et al.*, 2007*b*) have been described in the literature. Here we report the crystal structure of the title compound, 2-(4-iodophenyl)-5,7-dimethyl-3-methylsulfinyl-1-benzofuran (Fig. 1).

The benzofuran unit is essentially planar, with a mean deviation of 0.01 Å from the least-squares plane defined by the nine constituent atoms. The molecular packing (Fig. 2) is stabilized by three different C---H···O hydrogen bonds; one between a methyl H atom and the furan O atom, *i.e.* C16---H16B···O1, and a second between a methyl H atom and the oxygen of a neighbouring S═O unit, *i.e.* C16---H16A···O2^i^, and a third between a methyl H atom of the methylsulfinyl substituent and the furan O atom of neighbouring molecules, *i.e.* C17---H17B···O1^ii^, (Fig. 2 and Table 1; symmetry code as in Fig. 2). Further stabilization of the structure comes from a weak I···O halogen bond (Fig. 2) (Politzer *et al.*, 2007) between the iodine atom and the oxygen of a neighbouring S═O unit, with an I···O2^iii^ distance of 3.145 (2) Å (Symmetry code as in Fig. 2).

Experimental {#experimental}
============

77% 3-chloroperoxybenzoic acid (359 mg, 1.60 mmol) was added in small portions to a stirred solution of 2-(4-iodophenyl)-5,7-dimethyl-3-methylsulfanyl-1-benzofuran (591 mg, 1.50 mmol) in dichloromethane (30 ml) at 273 K. After being stirred at room temperature for 2 h, 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 (ethyl acetate) to afford the title compound as a colorless solid \[yield 80%, m.p. 450--451 K; *R*~f~ = 0.57 (ethyl acetate)\]. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of the title compound in tetrahydrofuran at room temperature. Spectroscopic analysis: ^1^H NMR (CDCl~3~, 400 MHz) δ 2.44 (s, 3H), 2.53 (s, 3H), 3.10 (s, 3H), 7.03 (s, 1H), 7.59 (d, J = 8.44 Hz, 2H), 7.80 (s, 1H), 7.84 (d, J = 8.44 Hz, 2H); EI---MS 410 \[*M*^+^\].

Refinement {#refinement}
==========

All H atoms were geometrically located in ideal positions and refined using a riding model, with C---H = 0.95 Å for aromatic H atoms and 0.98 Å for methyl H atoms, and with *U*~iso~(H) = 1.2Ueq(C) for aromatic H atoms, and 1.5Ueq(C) for methyl H atoms.

  Geometry. All e.s.d.\'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.\'s are taken into account individually in the estimation of e.s.d.\'s in distances, angles and torsion angles; correlations between e.s.d.\'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.\'s is used for estimating e.s.d.\'s involving l.s. planes.
  Refinement. Refinement of *F*^2^ against ALL reflections. The weighted *R*-factor *wR* and goodness of fit *S* are based on *F*^2^, conventional *R*-factors *R* are based on *F*, with *F* set to zero for negative *F*^2^. The threshold expression of *F*^2^ \> σ(*F*^2^) is used only for calculating *R*-factors(gt) *etc*. and is not relevant to the choice of reflections for refinement. *R*-factors based on *F*^2^ are statistically about twice as large as those based on *F*, and *R*- factors based on ALL data will be even larger.
