| 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. |
| Application: | 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 |
