5-Chloro-2-phenyl-3-phenyl-sulfinyl-1-benzofuran
Abstract:
In the title compound, C(20)H(13)ClO(2)S, the O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment; the S-bound phenyl ring is nearly perpendicular to this plane [80.87 (5)°]. The phenyl ring in the 2-position is rotated out of the benzofuran plane, making a dihedral angle of 17.43 (7)°. The crystal structure features π-π inter-actions between the phenyl ring and the furyl ring of a neighbouring benzofuran system [centroid-centroid distance = 3.886 (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...
