Lithium Aluminium Hydride is used to reduce carboxylic acids, esters, and acid halides to their corresponding primary alcohols. For example, LiAlH4 reduction of acetic acid, methyl acetate, and acetyl chloride yield the same ethyl alcohol. 3. Lithium aluminium hydride, LiAlH4, reduces the amides to amines.

It was discovered by Finholt, Bond and Schlesinger in 1947.[2] 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 gaseoushydrogen (H2). Some related derivatives have been discussed for hydrogen storage.
