3-(4-Chloro-phenyl-sulfon-yl)-2-methyl-naphtho[1,2-b]furan.

ABSTRACT: The title compound, C(19)H(13)ClO(3)S, was prepared by the oxidation of 3-(4-chloro-phenyl-sulfan-yl)-2-methyl-naphtho[1,2-b]furan with 3-chloro-peroxy-benzoic acid. The 4-chloro-phenyl ring makes a dihedral angle of 68.59?(5)° with the plane of the naphthofuran fragment. The crystal structure is stabilized by ?-? inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.635?(3)?Å], and by C-H?? inter-actions between a methyl H atom and the furan ring of an adjacent mol-ecule. In addition, the crystal structure exhibits inter-molecular C-H?O inter-actions.
