Abstract:
In the title compound, C21H21BrO3S, the cyclo-hexyl ring adopts a chair conformation. The dihedral angle between the mean planes of the benzo-furan and 2-bromo-phenyl fragments is 82.47 (5)°. In the crystal, mol-ecules related by inversion are paired into dimers via C-H⋯π and π-π inter-actions, the latter are indicated by the short distance of 3.607 (3) Å between the centroids of the furan rings. Inter-molecular C-H⋯O hydrogen bonds and short Br⋯O [3.280 (1) Å] contacts further consolidate the crystal packing.

For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
