4-Methylmorpholine N-oxide monohydrate, 98+%


Proprietà chimiche

Peso formula
135.17 (117.15anhy)
Punto di fusione
Soluble in water.


4-Methylmorpholine N-oxide monohydrate is used as a solvent to prepare cellulose fibers. It is an oxidant and involved in the catalytic OsO4 oxidation of olefins to cis-1,2-diols. It is also involved in ruthenium catalyzed oxidation of alcohols to aldehydes and ketones.


Hygroscopic. Store in a cool place. Keep the container tightly closed. Incompatible with strong oxidizing agents.

For use in the asymmetric dihydroxylation (ADH) reaction, catalyzed by Osmium(VIII)­ oxide, 12103, see: J. Am. Chem. Soc., 110, 1968 (1988); Org. Synth. Coll., 9, 383 (1998).

In the presence of Ru catalysts such as RuCl3 or Dichlorotris(triphenyl­phosphine)­ruthenium(II)­, L00373, oxidizes various types of alcohol to carbonyl compounds: Tetrahedron Lett., 2503 (1976). See also Tetra-n-propyl­ammonium perruthenate(VII)­, B24511.

In the presence of 4A molecular sieves in acetonitrile, activated (e.g. benzylic) halides can be oxidized to aldehydes and ketones: Synth. Commun., 22, 1967 (1992).

Boronic esters formed by treatment of aryl bromides in THF with n-BuLi, followed by trimethyl borate, can be oxidized in situ to phenols without isolation of the boronic acid: Synlett, 931 (1995).
