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.
