Product funtion:

Sodium borohydride (NaBH4) is a mild reducing agent that is typically used to reduce aldehydes and ketones to their respective alcohols. NaBH4 is sometimes used to reduce esters to alcohols but the reaction is generally slow. This difference in reactivity usually allows for the selective reduction of aldehydes and ketones in the presence of esters. Carboxylic 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. Sometimes THF is used as a solvent, either alone or as a solvent mixture (ex. THF/MeOH or THF/EtOH). In MeOH and EtOH, NaBH4 decomposes over time to give the respective borates. An excess of NaBH4 can be used to compensate for the decomposition of the reagent over time.
