Abstract
1) Mechanisms of alkaline decomposition were observed of arylmercapto- and arylsulfone-ketones.
2) Halogenation of arylmercapto-acetone results in the substitution of halogen atom in the methylene radical situated next to S-atom. In the case of arylsulfone-acetone, however, halogen goes in the methylene radical next to -SO2- group which, under the presence of hydrogen halides, transits in majority of cases to the methyl radical at the end.
3) Halogen compounds of arylmercapto-ketone are generally unstable and decomposes upon heating with alcohol.
