Abstract:
In the title compound, C21H14FIO2S, the dihedral angles between the mean plane [r.m.s. deviation = 0.007 (1) Å] of the benzo-furan fragment and the pendant 4-fluoro-phenyl and phenyl rings are 3.66 (7) and 82.37 (6)°, respectively. In the crystal, mol-ecules are linked by pairs of C-H⋯I hydrogen bonds into centrosymmetric dimers, which are further packed into stacks along the b axis by C-H⋯O hydrogen bonds. In addition, the stacked mol-ecules exhibit inversion-related S⋯O contacts [2.9627 (14) Å] involving the sulfinyl groups.

Nomenclature of Aromatic Compounds with Multiple Substituents
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...
