Can NaBH4 reduce imines?

Yes, NaBH4 can be used as a reducing agent. Therefore, it can be effective in reducing imine.

What does NaBH4 do to an imine?

After the imine is formed, it must be reduced to the amine. It’s possible to use the familiar reducing agent sodium borohydride (NaBH4) for this process. You may recall that NaBH4 is used for the reduction of aldehydes and ketones.

How do you reduce imine bond?

These include pressure hydrogenation using H2 gas, asymmetric transfer hydrogenation (ATH) using organic molecules as the reducing agent and organocatalytic reduction by using chiral reagents and these are probably the most common methods used to achieve reduction of imines to optically active chiral amines.

What happens when you reduce an imine?

Reduction of imines. A nickel-catalyzed enantioselective transfer hydrogenation of N-sulfonyl imines offers excellent α-selectivity. The use of inexpensive 2-propanol-d8 as a deuterium source enables a deuteration with high deuterium content.

Can NaBH4 reduce conjugated double bonds?

Originally Answered: Why does NaBH4 reduce its double bond? No, alone cannot reduce a double bond.

Can you reduce an imine?

These imines or enamines can be reduced to 2° or 3° amines, respectively. One way is hydrogen addition using a metal catalyst. The mechanism for the use of a non-‐metal-‐hydride as the reducing agent is shown above. This synthesis procedure requires the formation of an intermediate imine.

Does h2 Pd C reduce imine?

Reduction Of Other Multiple Bonds With Pd/C And Hydrogen Pd/C and hydrogen will also reduce other multiple bonds, such as NO (nitro groups), CN (nitriles) and C=NR (imines). Finally, if enough heat and pressure is added, Pd/C and hydrogen gas will also reduce aromatic groups such as benzene.

Which bonds does NaBH4 reduce?

Sodium borohydride is a good reducing agent. Although not as powerful as lithium aluminum hydride (LiAlH4), 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).
