Application

4-Methylmorpholine N-oxide (MNO) monohydrate can be used:
  • As a reagent in the dihydroxylation and aminohydroxylation of olefins in the presence of osmium tetroxide (OsO4) catalyst.
  • In the selective oxidation of sulphides to sulfoxides or sulfones in the presence of manganese and copper complexes with tetradentate ligands.

Other Notes

Reagent for an improved catalytic OsO4 oxidation of olefins to cis-1,2-diols; Review; For a ruthenium catalysed oxidation of alcohols to aldehydes and ketones
