چکیده
In the title compound, C(15)H(17)BrO(3)S, the cyclo-hexyl ring adopts a practically undistorted chair conformation [endocyclic torsion angles are within a 54.5-56.4 (3)° range] and the aryl-sulfonyl unit is positioned equatorial relative to the cyclo-hexyl group. In the crystal, mol-ecules are linked through C-H⋯O hydrogen bonds and donor-acceptor Br⋯O contacts [3.250 (2) Å]. The crystal structure also exhibits aromatic π-π overlap between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.635 (2) Å].

The title compound, C(12)H(11)BrO(4)S, was synthesized by the oxidation of methyl 2-(5-bromo-3-methyl-sulfanyl-1-benzofuran-2-yl)acetate with 3-chloro-peroxy-benzoic acid. The O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran ring system. The crystal structure is stabilized by C-H⋯π inter-actions, involving a methyl H atom and th...
