with potassium t-butoxide in t-butyl alcohol to give aryl cyclopropyl sulphones in high yields. The effects of substituents in the aromatic nucleus upon the rate of the reaction have been determined, and a rectilinear Hammettplot with ρ=+2·32 is obtained. Hydrogen atoms of the methylene group adjacent to the sulphonyl group are rapidly exchanged under basic conditions in deuteriated solvents, and
