Versuchsvorschrift

Acetonitrile (90 ml) was added to bis(p-tert-butylphenyl)iodonium chloride (6.4 g; 15 mmol) and methyl 9,10-dimethoxyanthracene-2-sulfonate (6.48 g; 19.5 mmol). The resultant mixture was heated at 82° C.-85° C. and refluxed for 20 hours while being stirred. The reaction mixture was cooled, and precipitated solid was separated through filtration. The solid was washed with ethyl acetate, and dried under vacuum, to thereby yield 8.32 g of bis(p-tert-butylphenyl)iodonium 9,10-dimethoxyanthracene-2-sulfonate (yield: 78%). The chloride anion content of the resultant solid was 110 ppm, as determined by silver nitrate titration.
