Abstract

Conclusions It appears that the only nucleophilic oxidation observed in this study is the oxidation of sulfoxides with mchloroperbenzoate anion. Therefore, even the Mo (V1)-peroxo anions formed in basic media oxidize the model sulfoxides via an electrophilic oxygen transfer, though less efficiently than the corresponding neutral species. This behavior has been previously observed in similar~ ystems.~ In the light of these results it appears rather ...
