✦ Synopsis

The s&ctivc oxidation of sulfides to sulfoxidcs by hydrogen peroxide under methylbioxorhenium(VIf) catalysis was examined; a high setcccivity of suifoxide over sulfone was achieved, except in the presence of water, which enhanced sulfonc formation.

The selective oxidation of sulfides to sulfoxides has been of continued interest, for which numerous methods have been developed.') Transition metai-catalyzed sulfoxidations have been reported for oxidants such as hydrogen peroxide?) iodosobenzene, *W iodylarenes,s) 02/isobutyraldehyde,4) and tBuOOH.5) Furthermore, enzyme catalysis has been employed in a number of cases.6)
