2-Phenyl-3-(phenyl-sulfin-yl)naphtho[1,2-b]furan.

In the title compound, C(24)H(16)O(2)S, the O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the naphthofuran fragment; the phenyl ring is almost perpendicular to this plane [81.54†(5)°]. The 2-phenyl ring is rotated out of the naphthofuran plane, making a dihedral angle of 18.2†(1)°.
