Lithium aluminium hydride

Lithium aluminum hydride is an inorganic compound. Its chemical formula is LiAlH₄. It is commonly abbreviated as LAH. It is a grey solid. It was discovered by Finholt, Bond and Schlesinger in 1947.^[1]

Properties

Lithium aluminium hydride is a colorless solid, but commercial samples are usually gray because of contamination.^[2] It can be purified by recrystallization from diethyl ether.^[2] It reacts violently with water.^[2] Some commercial samples contain mineral oil to stop reactions with moisture in the atmosphere.^[2]

Uses

Lithium aluminum hydride is used in organic chemistry as a reducing agent.^[2] Lithium aluminum hydride is most commonly used for the reduction of esters and carboxylic acids to primary alcohols.^[3]
