Reaktionsschritte

Tetrahydrothiophene (11.8 g) was dissolved in 100 ml of acetonitrile, and 20 g of 1-bromo-3,3-dimethyl-2-butanone was slowly added to the above solution. The reaction solution was stirred at room temperature for two days, thereby a powder was precipitated. After adding 100 ml of ethyl acetate to the reaction solution, the powder was filtered out, washed with ethyl acetate and dried, thereby 24 g of 2-oxo-3,3-dimethylbutyltetrahydrothiophenium bromide was obtained.
