Abstract:
The asymmetric unit of the title compound, C22H17FOS, contains two independent mol-ecules (A and B). The dihedral angles between the benzo-furan ring systems [r.m.s. deviations of 0.026 (1), 0.004 (1) and 0.003 (1) Å, respectively, for mol-ecule A, and 0.002 (1), 0.004 (1) and 0.005 (1) Å for B] and the pendant 4-fluoro-phenyl and 4-methyl-phenyl rings are 39.48 (4) and 30.86 (5)°, respectively, for mol-ecule A, and 33.34 (6) and 20.99 (8)° for B. In the crystal, mol-ecules are linked by weak C-H⋯F and C-H⋯π inter-actions, resulting in a three-dimensional network.

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...
