Imine

An imine ( or ) is a functional group or chemical compound containing a carbonnitrogen double bond, with the nitrogen atom attached to a hydrogen atom (H) or an organic group. If this group is ''not'' a hydrogen atom, then the compound can sometimes be referred to as a Schiff base. The carbon atom has two additional single bonds.〔March Jerry; (1985). ''Advanced Organic Chemistry reactions, mechanisms and structure'' (3rd ed.). New York: John Wiley & Sons, inc. ISBN 0-471-85472-7〕〔Fletcher, Dermer, Fox, ''Nomenclature of Organic Compounds'' (1974) 〕
== Nomenclature and classification==
Imines are related to ketones and aldehydes by replacement of the oxygen with an NR group. When R = H, the compound is a primary imine, when R is hydrocarbyl, the compound is a secondary imine. Imines exhibit diverse reactivity and are commonly encountered throughout chemistry.〔 When R3 is OH, the imine is called an oxime, and when R3 is NH2 the imine is called a hydrazone.
A primary imine in which C is attached to both a hydrocarbyl and a H is called a primary aldimine; a secondary imine with such groups is called a secondary aldimine. A primary imine in which C is attached to two hydrocarbyls is called a primary ketimine; a secondary imine with such groups is called a secondary ketimine.

One way of naming aldimines is to take the name of the radical, remove final "e", and add "-imine", for example ethanimine. See the aldimine article for other naming conventions. Alternately, an imine is named as a derivative of a carbonyl, adding the word "imine" to the name of a carbonyl compound whose oxo group is replaced by an imino group, for example sydnone imine and acetone imine (an intermediate in the synthesis of acetone azine).
N-Sulfinyl imines are a special class of imines having a sulfinyl group attached to the nitrogen atom.
