2,5,7-Trimethyl-3-phenylsulfinyl-1-benzofuran
نویسندگان
چکیده
The title compound, C(17)H(16)O(2)S, was prepared by the oxidation of 2,5,7-trimethyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment. The phenyl ring is nearly perpendicular to the plane of the benzofuran unit [88.30 (9)°] and is tilted slightly towards it. No π-π or C-H⋯π inter-actions are observed between neighbouring mol-ecules in the crystal structure because of steric hindrance induced by the three methyl groups.
