Reaction Steps

The synthesis was carried out under radiation from a yellow lamp. The synthesis was similar to the “Synthesis 5” except that the potassium trifluoromethanesulfonate and the 2-oxo-3,3-dimethylbutyl-thiacyclopentanium bromide were replaced with potassium nonafluorobutanesulfonate and 2-oxo-3,3,-dimethylbutyl-thiacyclopentanium bromide, respectively. The present inventors obtained 2-oxo-3,3-dimethylbutyl-thiacyclopentanium nonafluorobutanesulfonate. The yield was 52%, and the melting point was 79.5 degrees in centigrade.
