Versuchsvorschrift

To an ice cold suspension of 2-(difluoromethoxy)phenol (6.54 g, 0.00408 mol), aluminum trichloride (0.0544 g, 0.000408 mol) and 1,1′-thiodibenzene (0.068 mL, 0.000408 mol) was added sulfuryl dichloride (3.61 mL, 0.0449 mmol) dropwise. The reaction was allowed to warm to room temperature and stirred for 16 hours. The reaction was diluted in dichloromethane (10.0 mL) and purified using silica gel column chromatography eluting with 0-20% EtOAc in heptane. The title compound was isolated as a colourless oil (2.33 g, 0.01195 mol, 29%).
