Aluminium borohydride, also known as aluminium tetrahydroborate, is the chemical compound with the

covalent compound.[2][3]

Preparation

Aluminium borohydride is formed by the reaction between sodium borohydride with aluminium chloride:[4]

3 NaBH4 + AlCl3 → Al(BH4)3 + 3 NaCl

or as the non-pyrophoric tetrahydrofuran (THF) adduct, by the analogous reaction of calcium borohydride and aluminium chloride in THF:[2]

3 Ca(BH4)2 + 2 AlCl3 → 3 CaCl2 + 2 Al(BH4)3

Reactions

Like all borohydrides, this compound is a reducing agent and hydride donor. It reacts with water to give elemental

carboxylic esters, aldehydes, and ketones to alcohols.[2]
