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 ?-? 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?? and inter- and intra-molecular C-H?O inter-actions.

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 benze  ...[more]
