Reaktionsschritte

Subsequently, 2 g of thianthrene-S-oxide was dissolved in 10 ml of toluene and ice-cooled, and 2.8 ml of trifluoroacetic anhydride and 1.2 ml of nonafluorobutanesulfonic acid were added thereto, followed by stirring for 1 hour. Furthermore, diisopropyl ether was added thereto and after removing the supernatant, the residue was purified through a silica gel column (chloroform/methanol=19/1) to obtain 4.4 g of 5-(p-tolyl)thianthrenium nonafluorobutanesulfonate.
