Ketone react with secondary amine
Web8 nov. 2024 · The direct reductive amination of ketones (DRAK) is a multi-step process in which the amination agent, catalyst, and reaction conditions are closely related to one another. In DRAK, the amine undergoes arylation by a ketone in the presence of a hydrogen acceptor. The reaction proceeds via two consecutive steps.
