نویسندگان
چکیده
In the title compound, C(19)H(13)BrO(2)S, the O atom and the methyl group of the methyl-sulfinyl substituent lie on opposite sides of the plane of the naphthofuran unit. The phenyl ring is rotated out of the naphthofuran plane, making a dihedral angle of 42.2 (1)°. The crystal structure is stabilized by two inter-molecular C-H⋯π inter-actions, and by non-classical inter-molecular C-H⋯O and C-H⋯Br hydrogen bonds.
