Borohydride reduction reaction

WebSodium 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. WebImage 1: sodium borohydride has two practical uses in reduction reactions, reduction of aldehydes (like in this reaction) and ketones. The reactivity of sodium borohydride is too low to reduce carboxylic acids, amides, and esters 2.
