Versuchsvorschrift
To a solution of 6-bromo-naphthalen-2-ol (5 g, 22.4 mmol, Aldrich) in dry DMF (50 mL, Aldrich) was added N-fluorobenzene sulfonimide (21.9 g, 67.2 mmol, Aldrich). The reaction was stirred at RT for 48 h. The volatile portion was removed in vacuo and the residue was purified by silica gel chromatography (CHCl3) to give title compound as a yellow solid. MS (ESI, neg. ion) m/z: 240.0 (M−1). Mass Calc'd for C10H6BrFO: 239.96.
