Carboxylic acid with nabh4
WebCarboxylic acids can be converted to 1 o alcohols using Lithium aluminium hydride (LiAlH 4). Note that NaBH 4 is not strong enough to convert carboxylic acids or esters to alcohols. … WebCarboxylic acids, nitriles, and amides are not reduced by NaBH4 under normal conditions. However, carboxylic acids can be reduced by NaBH4 if they have been activated by an appropriate activating agent. NaBH4 is also occasionally used for reductive aminations. NaBH4 is usually used in hydroxylic solvents such as MeOH, EtOH, and H2O.
