imine

The reaction can also be performed with a pre-formed imine.

Elimination of water in the hemiaminal to the imine is not observed.

With primary amines water is lost in an elimination reaction to an imine.

The chain on the nitrogen makes the Schiff base a stable imine.

The methylamine-derived ammonia is then released, restoring the original imine.

This usually will rearrange to the imine; however there are several exceptions (such as aniline).

It is well known that a Schiff base is more stable than a regular imine.

In a representative application, is used to convert an imine into a NTf group.

In the first step phenylhydrazine is condensed with cyclohexanone to the corresponding imine.

The imine is often generated in situ from an amine and formaldehyde.

The reaction centers around an imine - lithium enolate cycloaddition.

This section describes some of these systems and is organized by the substitution pattern of the imine.

A key step in its industrial production involves the enantioselective reduction of an N-aryl imine.

While alkyllithiums are strong bases, they may react with the imine group, and are thus not appropriate.

The synthesis proceeds via the enantioselective hydrogenation of an imine (figure 2).

The resulting imine is hydrogenated to give primarily the S-stereoisomeric amine.

A nitrone is the N-oxide of an imine and a functional group in organic chemistry.

Ethanimine is an organonitrogen compound classified as an imine.

The ideal conditions for imine hydrogenation depend on the nature of the substrate and catalyst system.

However, it is also possible to carry out the same reaction simultaneously, with the imine formation and reduction occurring concurrently.

In the aza-Baylis-Hillman reaction the electrophile is an imine.

Hydrolysis of the imine yields an aldehyde and ammonia.

An imine is an intermediate in reductive amination.

In the case of a primary amine, a water molecule can be eliminated from the carbinolamine to yield an imine.

The imine is then hydrolyzed to the corresponding aldehyde/amine.
