7-Bromo-2-methyl-1-(phenyl-sulfon-yl)naphtho[2,1-b]furan
Abstract:
The title compound, C(19)H(13)BrO(3)S, was prepared by the oxidation of 7-bromo-2-methyl-1-(phenyl-sulfan-yl)naph-tho[2,1-b]furan with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 80.4 (2)° with the plane of the naphthofuran fragment. The crystal structure is stabilized by aromatic π-π stacking inter-actions between the brominated benzene ring and the central benzene ring of the naphthofuran system of neighbouring mol-ecules; the centroid-centroid distances within the stack are 3.889 (3) and 3.981 (3) Å. In addition, the stacked mol-ecules exhibit C-H⋯π, inter- and intra-molecular C-H⋯O inter-actions.

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...
