Application

  • 4-Methylmorpholine N-oxide (NMO) is widely used as a co-oxidant to regenerate osmium tetroxide (OsO4) catalyst during dihydroxylation of alkenes.
  • In the presence of catalytic amounts of tetra-n-propylammonium perruthenate (TPAP), NMO oxidizes secondary amines to the corresponding imines.
  • 4-Methylmorpholine N-oxide solution can be used to oxidize activated primary halides to aldehydes and secondary halides to ketones, respectively.
  • It can also be used to promote stereoselective intermolecular Pauson-Khand reaction for the synthesis of cyclopentenones.

Oxidant for synthesis of novel organic polymer - inorganic hybrid for use as a catalyst for asymmetrical epoxidation

Reagent or Reactant for:
  • Cyclocondensation and cyclization in the enantioselective synthesis of oxazolomycin A
  • Wharton rearrangement and stereoselective dihydroxylation reactions
  • Reduction of amine N-oxides by diboron reagents
  • Synthesis of polysaccharide blend fibers
  • Synthesis of cellulose / modified nano-SiO2 composite packaging films
  • Copper-catalyzed oxidative coupling for preparation of propargylamines

Used as a pretreatment for techno-economical study of ethanol and biogas production from spruce wood
