Reaction Conditions

Reaction Steps

To a solution of 25.4 mmol 3,3,3-trifluoro-1-(phenylsulphonyl)prop-1-ene in 80 ml acetonitrile were added 30.5 mmol peracetic acid (39% solution in acetic acid) and 101 mmol potassium carbonate. The mixture was heated at 60° C. for 4 h. The reaction mixture was then diluted with ethyl acetate/tetrahydrofuran (1:1) and was washed with brine. The organic phase was dried over sodium sulfate and concentrated in vacuo to afford the title compound as a light yellow crystalline solid (yield 90%). EI-MS (m/e): 252.0 (M+, 15%), 125.1 (PhSO+, 100%), 77.2 (Ph+, 37%).
