The Synthesis and Testing of Differential Herbicides
This investigation was limited to the preparation of substituted phenoxyacetic acids and related compounds. The types of substances prepared for testing can, in general, be placed in three groups. These are: aryloxyacetic acids, arylmercaptoacetic acids, and those acids containing the thiophene nucleus.

A-(Substitutedbenzenesulfonyl)-Substitutedacetophenones
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.

Synthesis of a-(p-Aminophenylsulfonyl)-Substitutedacetophenones
This thesis describes a procedure used to synthesize a-(p-Aminophenylsulfonyl)-p-methylacetophenone, a-(p-aminophenylsulfonyl)-p-bromoacetophenone, and a-(p-aminophenylsulfonyl)-p-methoxyacetophenone for study as possible new anti-tubercular agents.
