7-Bromo-2-methyl-1-tosyl-naphtho[2,1-b]furan
Abstract:
The title compound, C(20)H(15)BrO(3)S, was prepared by the oxidation of 7-bromo-2-methyl-1-(4-tolyl-sulfan-yl)naph-tho[2,1-b]furan with 3-chloro-peroxy-benzoic acid. The 4-tolyl ring makes a dihedral angle of 70.96 (6)° with the plane of the naphthofuran fragment. The crystal structure is stabilized by aromatic π-π stacking inter-actions, with centroid-centroid distances of 3.672 (3) and 3.858 (3) Å between the central benzene and furan rings, and between the brominated benzene and central benzene rings of the naphthofuran system of neighbouring mol-ecules, respectively. In addition, the stacked mol-ecules exhibit C-H⋯π and inter- and intra-molecular C-H⋯O inter-actions.

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...
