Synthesis of 3,3,-dimethylbutyraldehyde by the reduction of 3,3,-dimethylbutyric acid

摘要

A process for the production of 3,3-dimethylbutyraldehyde is disclosed. The 3,3-dimethylbutyraldehyde is obtained by the reduction of 3,3-dimethylbutyric acid using trimethylacetic anhydride and a phosphine. The 3,3-dimethylbutyric acid is preferably obtained by a process in which tert-butanol and vinylidene chloride are reacted in the presence of sulfuric acid. The disclosed process has improved cost and yield.
