Aldimine

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.

An important subset of aldimines are the Schiff bases, in which the substituent on the nitrogen atom (R') is an alkyl or aryl group (i.e. not a hydrogen atom).

Nomenclature
Aldimines may be named in three different manners: An obsolete nomenclature treats aldimines as derivatives of a parent aldehyde.
 * 1) by replacing the final -e of the parent hydride, R–CH3, with the suffix "-imine";
 * 2) as alkylidene derivatives of azane;
 * 3) (rare) as alkylidene derivatives of "amine".
