実験手順
In 93 g of methanol was dissolved 9.3 g (0.018 mol) of tris(4-tert-butoxyphenyl)sulfonium chloride. 3.5 g (0.013 mol) of lead carbonate and 3.0 g (0.022 mol) of butanesulfonic acid were added to the solution, which was heated at 50 ° C. After cooling, the precipitate was filtered off and the filtrate was evaporated. Then 100 g of chloroform was added to the residue, the solution was washed with 100 g of water, and the solution was evaporated again, obtaining 9.2 g (two-steps yield 29%) of tris(4-tert-butoxyphenyl)sulfonium butanesulfonate with 97% purity.
