Abstract
Abstract The reactions of the arylsulfinic acid salts with alkyl chlorocarbonates in various alcohols as solvents gave the alkyl sulfinates, in which the alkoxyl groups originated from the solvent alcohols, not from the chlorocarbonates. Sodium p-toluenesulfinate-18O and ethyl chlorocarbonate in a large excess of methanol gave methyl p-toluenesulfmate-18O, which was shown to contain about half of the 18O atoms of the starting salt. The mixed anhydride of sulfinic acid and monoalkyl carbonate is postulated as an intermediate, the alcoholysis of which would give the sulfinate ester. Reactions have been studied also in the nonhydroxylic solvents.
