WitrynaReductive amination with zinc powder in aqueous media. Reductive amination is the name usually employed to indicate a synthetic protocol for the preparation of amines that involves a two-step reaction between a carbonyl compound and a primary or secondary amine (or even ammonia or ammonium salts), in the presence of a selective … WitrynaImines from Primary Amines – The Mechanism. There are two main parts in the net transformation; 1) nucleophilic addition of the primary amine and 2) elimination of H2O. All the steps are reversible, and the overall equilibrium of the reaction is shifted by removing H 2 O as we have also seen in the reaction of aldehydes and ketones with …

Witryna23 kwi 2024 · Atom-economical imine reduction: Classical imine-to-amine reduction uses stoichiometric quantities of LiAlH 4, which generates Li/Al salt side products. The same reaction under an H 2 atmosphere needs only catalytic LiAlH 4 (2.5 mol %) and proceeds under surprisingly mild conditions (85 °C, 1 bar H 2 ). In organic chemistry, an imine is a functional group or organic compound containing a carbon–nitrogen double bond (C=N). The nitrogen atom can be attached to a hydrogen or an organic group (R). The carbon atom has two additional single bonds. Imines are common in synthetic and naturally occurring compounds and they participate in many reactions.
