2,5,7-Trimethyl-3-phenyl-sulfinyl-1-benzo-furan
Abstract:
The title compound, C(17)H(16)O(2)S, was prepared by the oxidation of 2,5,7-trimethyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The phenyl ring is nearly perpendicular to the plane of the benzofuran unit [88.30 (9)°] and is tilted slightly towards it. No π-π or C-H⋯π inter-actions are observed between neighbouring mol-ecules in the crystal structure because of steric hindrance induced by the three methyl groups.

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...
