Lithium aluminum hydride
Application | ||
|---|---|---|
Lithium aluminium hydride is used in organic and inorganic fine chemical synthesis as a powerful reducing agent. It reduces esters and carboxylic acids to primary alcohols and reduces epoxides to secondary or tertiary alcohols. It reduces nitro compounds (amides and alkyl azides) into amine. It is also used to reduce alkyl halides and alkynes but is not available to reduce alkenes or benzene rings. It can reduce aldehyde ketone, acid, acid anhydride, ester, quinone and acyl chloride into alcohol, reduce nitrile into primary amine, halogenated hydrocarbon into hydro carbon |
Description | ||
|---|---|---|
Lithium aluminum hydride, commonly abbreviated to LAH, is an inorganic compound with the chemical formula Li[AlH4] or LiAlH4. It is a white solid, discovered by Finholt, Bond and Schlesinger in 1947. This compound is used as a reducing agent in organic synthesis, especially for the reduction of esters, carboxylic acids, and amides. The solid is dangerously reactive toward water, releasing gaseous hydrogen (H2). Some related derivatives have been discussed for hydrogen storage. |
