WitrynaDoes NaBH4 affect esters? Although not as powerful as lithium aluminum hydride (LiAlH 4), it is very effective for the reduction of aldehydes and ketones to alcohols.By itself, it will generally not reduce esters, carboxylic acids, or amides (although it will reduce acyl chlorides to alcohols)..

WitrynaThe mechanism of sodium borohydride reduction of a ketone or aldehyde is very similar to that for hydroboration of a C=C bond: Note that all four hydrogen atoms in the borohydride reagent are available as hydrides (H:-), and thus one equivalent of borohydride can reduce four equivalents of ketone. All the steps are irreversible. WitrynaThe carbon bonded to the OH, is bonded to two other carbons. That's formation of a secondary alcohol, reduction of a ketone to form a secondary alcohol. Another hydride reducing agent is lithium aluminum hydrides. Let's look at this reaction here. We have lithium aluminum hydride.
