2-(4-Fluoro-phen-yl)-5-iodo-3-phenyl-sulfinyl-1-benzofuran
Abstract:
In the title compound, C(20)H(12)FIO(2)S, the dihedral angles between the mean plane [r.m.s. deviation = 0.014 (1) Å] of the benzofuran fragment and the pendant 4-fluoro-phenyl and phenyl rings are 8.0 (1) and 86.06 (6)°, respectively. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds. The crystal structure also exhibits weak π-π inter-actions between the furan and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.547 (2) Å, inter-planar distance = 3.397 (2) Å and slippage = 1.021 (2) Å].

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...
