A 3.30 g (0.01 mole) sample of triphenylcarbenium tetrafluoroborate is added to a solution 3.92 g of 2-(4-methylphenyl)-1,3-dithiolane in 35 ml of acetonitrile under nitrogen at 5° C. Methylene chloride is added then ether. The yellow solid is collected and washed with ether. There is obtained 0.7 g (14% yield) of 2-(4-methylphenyl)-1,3-dithiolanium fluoroborate, m.p. 119°-120° C.
