α-Sulfinylcarbanions (<B>1</B>) derived from methyl-substituted sulfoxides readily react with arenesulfinic esters (<B>2</B>) to give the corresponding β-disulfoxides (<B>3</B>) in good yields. The reaction was conducted using (−)-menthyl (−)-(<I>S</I>)-benzenesulfinate ((−)-(<I>S</I>)-<B>2b</B>), (−)-menthyl (−)-(<I>S</I>)-<I>p</I>-toluenesulfinate ((−)-(<I>S</I>)-<B>2c</B>), and α-<I>p</I>-tolylsulfinylcarbanion derived from (+)-(<I>R</I>)- or (−)-(<I>S</I>)-methyl <I>p</I>-tolyl sulfoxide to produce (<I>R</I>,<I>S</I>)- and/or (<I>S</I>,<I>S</I>)-diastereoisomers of five β-disulfoxides (<B>3a</B>–<B>e</B>). The configurational assignment for the diastereoisomers obtained was accomplished by a combination of NMR and polarimetric analyses.
