Imine bonds
WitrynaMechanism and stereochemistry []. Hydrogen for the reduction of C=N double bond can either be provided by hydrogen gas (H 2) or transferred from sources of H 2, such as alcohols and formic acid.The process is usually catalyzed by transition metal complexes.For metal catalyzed reactions, the transfer of H 2 to the imine can … WitrynaFormation of an imine —from an amine and an aldehyde —is a reversible reaction which operates under thermodynamic control such that the formation of kinetically …
