ALUMINUM TERT-BUTOXIDE Chemical Properties,Usage,Production

Chemical Properties

slightly yellow crystalline powder

Uses

Aluminum tert-butoxide is utilized as a reagent in the Oppenauer oxidation of alcohols to ketones. It is also used in Meerwein-Ponndorf-Verley reduction of ketones. It is actively involved in the preparation of 1,1,2-triethoxyethene by reacting with 1,1,2,2-tetraethoxyethane followed by the elimination of alcohol.

Uses

Reagent for oxidation of alcohols to ketones; in dealcoholation of orthoesters.

Purification Methods

Crystallise it from *C6H6 and it sublimes it at 180o. [McElvain & Davie J Am Chem Soc 73 1400 1951, Beilstein 1 IV 1612.]
