Reduction of Esters and Nitriles by DIBAL H

Aldehydes can be produced by the reduction of both esters and nitriles using DIBAL H.

Reduction of Esters:
- When esters are treated with DIBAL H, they are reduced to aldehydes.
- The reaction proceeds via a two-step process where the ester is first converted to an aldehyde intermediate, which is then further reduced to the final aldehyde product.
- This reduction reaction is useful in organic synthesis to selectively produce aldehydes from esters.

Reduction of Nitriles:
- Similarly, nitriles can also be reduced to aldehydes using DIBAL H.
- Nitriles are first converted to imines, which are then reduced to aldehydes.
- This reaction provides a method for the conversion of nitriles to aldehydes in organic synthesis.

Conclusion:
- Therefore, the reduction of both esters and nitriles by DIBAL H can lead to the formation of aldehydes.
- This versatile reagent allows for the selective synthesis of aldehydes from these functional groups, providing a valuable tool for organic chemists.

Similar Class 12 Doubts

Read the passage given below and answer the following questions:Reductive alkylation is the term applied to the process of introducing alkyl groups into ammonia or a primary or secondary amine by means of an aldehyde or ketone in the presence of a reducing agent. The present discussion is limited to those reductive alkylations in which the reducing agent is hydrogen and a catalyst or "nascent" hydrogen, usually from a metalacid combination; most of these reductive alkylations have been carried out with hydrogen and a catalyst. The principal variation excluded is that in which the reducing agent is formic acid or one of its derivatives; this modification is known as the Leuckart reaction. The process of reductive alkylation of ammonia consists in the addition of ammonia to a carbonyl compound and reduction of the addition compound or its dehydration product. The reaction usually is carried out in ethanol solution when the reduction is to be effected catalytically:Since the primary amine is formed in the presence of the aldehyde it may react in the same way as ammonia, yielding an additional compound, a Schiff's base (RCH= NCH2R) and finally, a secondary amine. Similarly, the primary amine may react with the imine, forming an addition product which also is reduced to a secondary amine Finally, the secondary amine may react with either the aldehyde or the imine to give products which are reduced to tertiary amines.Similar reactions may occur when the carbonyl compound employed is a ketone.Q. The reaction of ammonia and its derivatives with aldehydes is called
