5-Chloro-2-methyl-3-phenyl­sulfonyl-1-benzofuran

The title compound, C(15)H(11)ClO(3)S, was prepared by the oxidation of 5-chloro-2-methyl-3-phenyl­sulfanyl-1-benzofuran with 3-chloro­peroxy­benzoic acid. There are two symmetry-independent mol­ecules 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 π–π stacking inter­actions between the furan ring and the benzene rings of neighbouring benzofuran fragments from two symmetry-independent mol­ecules; 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 mol­ecules exhibit inter- and intra­molecular C—H⋯O inter­actions.
