In organic chemistry, an aldimine is an imine that is an analog of an aldehyde. As such, aldimines have the general formula R–CH=N–R'. Aldimines are similar to ketimines, which are analogs of ketones.
|common usage||butyraldehyde imine||acetaldehyde N-methylimine|
Aldimines may be named in three different manners:
- by replacing the final -e of the parent hydride, R–CH3, with the suffix "-imine";
- as alkylidene derivatives of azane;
- (rare) as alkylidene derivatives of "amine".
An obsolete nomenclature treats aldimines as derivatives of a parent aldehyde.
