A-(Substitutedbenzenesulfonyl)-Substitutedacetophenones

Description: This thesis discusses the preparation of a-(o-nitro-p-methylphenylmercapto)-acetophenone by the reaction between acetophenone and o-nitro-p-methylbenzenesulfenyl chloride in boiling chloroform. The use of stannous chloride in glacial acetic acid for the reduction of nitro groups to amino groups was found generally satisfactory in spite of the difficulty often met with in isolating the amino product.
