WebIn the lithium aluminum hydride reduction water is usually added in a second step. The lithium, sodium, boron and aluminum end up as soluble inorganic salts at the end of either reaction. Note! LiAlH 4 and NaBH 4 are both capable of reducing aldehydes and ketones to the corresponding alcohol. Example 1: Mechanism WebIf we add lithium aluminum hydride in the first step and then a source of protons in the second step-- which is water-- we will form either a primary or a secondary alcohol, depending on our starting materials. So in that respect, lithium aluminum hydride will react in the same way as sodium borohydride.
