5-Chloro-2-methyl-3-phenyl-sulfonyl-1-benzofuran.

ABSTRACT: The title compound, C(15)H(11)ClO(3)S, was prepared by the oxidation of 5-chloro-2-methyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. There are two symmetry-independent mol-ecules in the asymmetric unit. The dihedral angles formed by the phenyl ring and the plane of the benzofuran system are 77.80?(8) and 78.34?(8)°. The crystal structure is stabilized by aromatic ?-? stacking inter-actions between the furan ring and the benzene rings of neighbouring benzofuran fragments from two symmetry-independent mol-ecules; the centroid-centroid distances within the stacks are 3.689?(4), 3.702?(4), 3.825?(4) and 3.826?(4)?Å. Additionally, the stacked mol-ecules exhibit inter- and intra-molecular C-H?O inter-actions.
