3-[(4-Fluoro-phen-yl)sulfon-yl]-5-iodo-2-methyl-1-benzofuran
Abstract:
In the title compound, C(15)H(10)FIO(3)S, the 4-fluoro-phenyl ring makes a dihedral angle of 72.27 (6)° with the mean plane of the benzofuran fragment [mean deviation of 0.014 (2) Å from the plane defined by the nine constituent atoms]. In the crystal, pairs of weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further linked via an aromatic π-π inter-actions between the iodo-benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.569 (3) 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...
