The title compound, C(18)H(18)O(3)S, was prepared by the oxidation of 5-isopropyl-2-methyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 79.37 (6)° with the plane of the benzofuran fragment. The crystal structure is stabilized by aromatic π-π stacking inter-actions between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.762 (3) Å]. In addition, the stacked mol-ecules exhibit C-H⋯π and intra-molecular C-H⋯O inter-actions.
标题化合物C(18)H(18)O(3)S是通过用3-氯过氧苯甲酸氧化5-异丙基-2-甲基-3-苯基硫烷基-1-苯并呋喃制备而成。苯环与苯并呋喃片段的平面形成79.37 (6)°的二面角。晶体结构通过相邻分子的苯环和呋喃环之间的芳香π-π堆积相互作用得以稳定[质心-质心距离 = 3.762 (3) Å]。此外，堆积的分子表现出C-H⋯π和分子内C-H⋯O相互作用。
