Oxidation mono-oxygen donor

Primary amines are oxidized to the corresponding oximes. The sequence of reactions closely parallels the sequence observed with other mono oxygen donors, i.e., oxidation to alkyl hydroxylamines (V) followed by oxidation to alkylnitroso compounds (VI) which, via a prototropic shift, rearrange to the oximes (VII) ... 

Summarizing the information disclosed in the section above, one notes that polyoxometalates appear to be versatile oxidation catalysts capable of activating various mono-oxygen donors such as iodosobenzene, periodate, ozone, nitrous oxide, and sulfoxides. Some of these reactions are completely new from both a synthetic and mechanistic point of view. The various reaction pathways expressed are also rather unusual and point to the many options and reaction pathways available for oxidation catalyzed by polyoxometalates. 

As has been mentioned in Section 2.3.1.12, many oxygen and nitrogen donor adducts are prepared from mono- and dihalobismuthines and structurally characterized. The oxygen donors include THF, triphenylphosphine oxide, triphenylarsine oxide, diphenyl sulfoxide, HMPA and, A -dimethyl-...
