Participants

Reaction Steps

A solution of 55.7 g (0.1 mol) of bis(p-tert-butoxyphenyl)phenylsulfonium trifluoromethanesulfonate and 1.5 g (0.01 mol) of trifluoromethanesulfonic acid in 500 g of methanol was heated at 60° to 70° C. for 7 hours with stirring. The reaction mixture was evaporated in vacuo. The residual oil was washed two times with 100 g of diethyl ether. The amount of this crude product was 42 g (94% yield).
