The reverse of imine formation is called imine hydrolysis, yielding the corresponding amine and carbonyl containing compound (aldehyde or ketone). In this process, the imine ...
Imines are typically prepared by the condensation of primary amines and aldehydes or ketones. Ketones undergo similar reactions, but less commonly than aldehydes. In terms of mechanism, such reactions proceed via the nucleophilic addition giving a hemiaminal -C(OH)(NHR)- intermediate, followed by an elimination of water to yield the imine (see alkylimino-de-oxo-bisubstitution fo…
