Abstract
It has been demonstrated that molybdenum(III) ion is effective for deoxygenation of sulfoxides.1 However, since this reagent was generated by treatment of molybdenyl chloride with zinc dust, the role of some suspended metal in the sulfoxide reduction cannot be assessed. In order to conclusively establish the reducing capability of low-valent molybdenum ions for sulfoxides we have carried out experiments with Mo species obtained in a manner that the suspicion of active metal participation is exonerated.
