Chlorosulfonic acid → 1261827-78-4

2-Fluoroiodobenzene (0.58 mL, 5.0 mmol) was added dropwise to chlorosulfonic acid (1.66 mL, 25 mmol) at 0° C. The reaction mixture was allowed to warm to ambient temperature and stirred for 2 hours. The reaction mixture was poured into ice and the mixture was extracted with dichloromethane (3×30 mL). The combined organic layer was dried over magnesium sulfate and concentrated in vacuo to obtain a crude residue. The crude residue was dissolved in heptane (100 mL) and the suspension was filtered. The filtrate was concentrated in vacuo to afford the title compound.
