Lithium aluminum hydride  ( lithium alanate ) is an inorganic compound, a complex mixed hydride of lithium and aluminum with the formula Li[AlH 4 ], white crystals. A strong reducing agent used in organic synthesis. More powerful than other commonly used agents, such as sodium borohydride, due to the weaker Al-H bonds compared to B-H. Reduces esters, carboxylic acids and ketones to alcohols, nitro compounds to amines.
