چکیده
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.

In the title compound, C20H15BrO2S, the dihedral angle between the mean plane [r.m.s. deviation = 0.030 (2) Å] of the naphtho-furan ring system and the 4-methyl-phenyl ring is 38.49 (9)°. In the crystal, mol-ecules are linked by C-H⋯π and C-Br⋯π [3.871 (2) Å] inter-actions into stacks along the b-axis direction. These stacks are further linked by weak C-H⋯O hydrogen bonds, forming a three-dimen...
