In the title compound, C(15)H(10)BrFO(2)S, the O atom and the methyl group of the methyl-sulfinyl substituent are located on opposite sides of the plane through the benzofuran fragment. The 4-fluoro-phenyl ring is rotated out of the benzofuran plane, as indicated by a dihedral angle of 26.23 (5)°. The crystal structure is stabilized by a non-classical inter-molecular C-H⋯O hydrogen bond and a Br⋯O halogen bond [3.163 (2) Å].
在标题化合物C₁₅H₁₀BrFO₂S中,甲基亚磺酰基取代基的O原子和甲基位于通过苯并呋喃片段的平面的相对两侧。4-氟苯基环旋转出苯并呋喃平面,二面角为26.23(5)°。晶体结构通过非经典的分子间C-H⋯O氢键和Br⋯O卤键[3.163(2)Å]得以稳定。
