It is a nucleophilic reducing agent, best used to reduce polar multiple bonds like C=O. Home. 1) Nucleophilic attach by the hydride . Conversion of Amides into Amines with LiAlH4 Last updated; Save as PDF Page ID 5891; Introduction; General Reaction; Mechanism; Contributors; Introduction.
lithium aluminium hydride, lialh4, lah, reduction mechanism, applications in modern organic synthesis as a reducing agent.
Mechanism. Amide Reduction Mechanism by LiAlH4. Amides, RCONR' 2, can be reduced to the amine, RCH 2 NR' 2 by conversion of the C=O to -CH 2- Amides can be reduced by LiAlH 4 but NOT the less reactive NaBH 4 Typical reagents : LiAlH 4 / ether solvent, followed by aqueous work-up.
General Reaction.
Amides can be reduced by LiAlH 4 but NOT the less reactive NaBH 4; Typical reagents : LiAlH 4 / ether solvent followedby aqueous work-up. Note that this reaction is different to that of other C=Ocompounds which reduce to alcohols; The nature of the amine obtained depends on …

If you wanted to reduce the carbonyl group of a ketone/aldehyde to a methylene group, the three most well-known methods available are the Wolff-Kishner reaction, the Clemmensen reduction, and the Mozingo reduction.
Example 1: Amide Reductions; Alkyl groups attached to the nitrogen do not affect the reaction. Sign up to join this community. It only takes a minute to sign up. A detailed mechanism illustrating the conversion of an amide to an amine using lithium aluminum hydride (LiAlH4). Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. Amides can be reduced to amines by LiAlH 4: Remember that reduction of all the other carboxylic acid derivatives containing a carbonyl group produces alcohols: Another exception are the nitriles, but these do not contain a carbonyl group and depending on the reducing agent, different products can be obtained.
