Description

General description

4-Methylmorpholine N-oxide is an organic compound used as a co-oxidant along with OsO₄ and ruthenates in organic synthesis. In recent studies, it has been used as a catalyst in silylcyanation of aldehydes and ketones. Lyocell, a regenerated cellulose fiber, can be prepared using 4-methylmorpholine N-oxide in an eco-friendly manner.

Application

Non-metallic catalyst for the cyanosilylation of ketones. Co-oxidant for Sharpless asymmetric dihydroxylation in ionic liquids.
