ABSTRACT:
Sodium 3,3-dimethyl-2-hydroxybutyrate and ruthenium dioxide hydrate are added to water, the pH rendered alkaline, and sodium hypochlorite is slowly added to produce sodium 3,3-dimethyl-2-oxobutyrate in high yield and purity. The solid catalyst is filtered off and may be re-used while the filtrate can be directly used in further synthesis.
