Descrizione

Applicazioni

• 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
