Abstract

Linalool is prepared by epoxidizing citral to the mono-a ,b -epoxide and reducing the epoxide with hydrazine to give linalool. Epoxidation is effected using an alkaline solution of hydrogen peroxide in the presence of an alkanol. The reduction of the epoxide may be carried out using a solution of hydrazine hydrate in an inert solvent, preferably in the presence of an acidic catalyst at temperatures below 30 DEG C. Examples are provided.
