The general structure of an enamine. An enamine is an unsaturated compound derived by the condensation of an aldehyde or ketone with a secondary amine. [1] [2] Enamines are versatile intermediates. [3] [4] Condensation to give an enamine. [5] The word "enamine" is derived from the affix en-, used as the suffix of alkene, and the root amine.
Acetone imine, or 2-propanimine is an organic compound and an imine with the chemical formula (CH 3) 2 CNH. It is a volatile and flammable liquid at room temperature . It is the simplest ketimine .
A general linear imide functional group. In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. [1] The compounds are structurally related to acid anhydrides, although imides are more resistant to hydrolysis.
When R = H, the compound is a primary imine, when R is hydrocarbyl, the compound is a secondary imine. If this group is not a hydrogen atom, then the compound can sometimes be referred to as a Schiff base. [9] When R 3 is OH, the imine is called an oxime, and when R 3 is NH 2 the imine is called a hydrazone.
Reaction of cyclohexylamine with acetaldehyde forming an imine. Sodium sulfate removes water [1] In organic chemistry, alkylimino-de-oxo-bisubstitution is the organic reaction of carbonyl compounds with amines to imines. [2] The reaction name is based on the IUPAC Nomenclature for Transformations.
The inorganic imide is an inorganic chemical compound containing an anion with the chemical formula HN 2− , in which nitrogen atom is covalently bonded to one hydrogen atom (as in lithium imide Li 2 NH and calcium imide CaNH ).
3:45 a.m.: Maui officials announce in a news release that a brush fire was reported in the Olinda Road area of Kula, an area in central Maui. The blaze would come to be known as the Upcountry Fire ...
The C=N bonds, which are near 129 picometers in length, are shorter than C-N single bonds. Cis/trans isomers are observed. The C=N distance is slightly shorter in iminium cations than in the parent imine, and computational studies indicate that the C=N bonding is also stronger in iminium vs imine, although the C=N distance contracts only slightly.
