Ethyl benzoyloxysulfinate, prepared from <SUP>18</SUP>O-labeled benzoic acid and ethyl chlorosulfite, was decomposed and the products were analyzed. The <SUP>18</SUP>O analyses showed that; 1) prior to decomposition the <SUP>18</SUP>O of the mixed anhydride was scrambled due to the formation and the internal return of an ion-pair, C<SUB>6</SUB>H<SUB>5</SUB>C<SUP>+−</SUP>OSOEt; 2) ethyl benzoate, benzoic anhydride and diethyl<BR>(<U>Remark: Graphics omitted.</U>)<BR>sulfite were produced <I>via</I> an ionic chain mechanism involving successive attack of ethoxide anion and benzoate anion on the carbonyl carbon and sulfinyl sulfur of the mixed anhydride.
