3-(3-Chloro-phenyl-sulfin-yl)-2,4,6,7-tetra-methyl-1-benzofuran
Abstract:
In the title compound, C(18)H(17)ClO(2)S, the 3-chloro-phenyl ring makes a dihedral angle of 72.62 (4)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O and C-H⋯π inter-actions. The crystal structure also exhibits a slipped π-π inter-action between the 3-chloro-phenyl rings of adjacent mol-ecules [centroid-centroid distance = 3.751 (2) Å, inter-planar distance = 3.450 (2) Å and slippage = 1.472 (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...
