5-Fluoro-2-methyl-3-phenyl-sulfonyl-1-benzofuran
Abstract:
There are two symmetry-independent mol-ecules, A and B, in the asymmetric unit of the title compound, C(15)H(11)FO(3)S. The crystal studied was an inversion twin with a 0.21 (12):0.79 (12) domain ratio. In the crystal structure, the two independent mol-ecules are related by a pseudo-inversion center. The dihedral angles formed by the phenyl ring and the plane of the benzofuran fragment are 80.2 (1)° in mol-ecule A and 80.7 (1)° in mol-ecule B. In the crystal structure, the A and B mol-ecules are linked by aromatic π-π inter-actions between the furan and benzene rings of neighbouring benzofuran systems; the centroid-centroid distances are 3.671 (7) and 3.715 (7) Å. In addition, the crystal structure also exhibits two weak non-classical inter-molecular C-H⋯O hydrogen bonds.

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...
