Use | N-methylmorpholine N-oxide, commonly abbreviated as NMO, is a metabolite of morpholine (M723725). N-methylmorpholine N-oxide is commonly used to solubilize cellulose and solubilize hard proteins. NMO is a non-metallic catalyst for the silocyanation of ketones. 1. The pro-oxidant NMO used for the asymmetric double hydroxylation of sharuss in ionic liquids is a non-metallic catalyst for the cyanosilylation of ketones. Co-oxidants for the warm and asymmetric dihydroxylation of ionic liquids. |
