実験手順

70.2 Parts of tetrahydrothiophene was dissolved in 750 parts of acetone, and 150 parts of 1-bromo-3,3-dimethyl-2-butanone was added dropwise thereto. After the mixture was stirred at room temperature for 24 hours, white solid obtained was filtered, washed with acetone and dried to obtain 161.3 parts of 1-(3,3-dimethyl-2-oxobutyl)tetrahydrothiophenium bromide in the form of white crystals.
