Participants

Reaction Steps

A solution of 5.8 g (0.01 mol) of bis(p-tert-butoxyphenyl)phenylsulfonium p-toluenesulfonate and 0.95 g (0.005 mol) of p-toluenesulfonic acid in 35 g of methanol was heated at 60° C. for 5 hours with stirring. The reaction mixture was evaporated in vacuo. The residual oil was washed two times with 200 g of diethyl ether. The amount of this crude product was 4.7 g (100% yield).
