Sodium Borohydride (NaBH4) As A Reagent In Organic Chemistry

Lithium aluminium hydride (LAH) is widely used in organic chemistry as a reducing agent. It is more powerful than the related reagent sodium borohydride owing to the weaker Al-H bond compared to the B-H bond. Often as a solution in diethyl ether and followed by an acid workup, it will convert esters, carboxylic acids, acyl chlorides, aldehydes, and ketones into the corresponding alcohols (see: carbonyl … Web11 jun. 2024 · The molar mass of this compound is 37.83 g/mol, and the melting point is 400 C.
