Method for the production of amines by reductive amination of carbonyl compounds under transfer-hydrogenation conditions
First Claim
1. A process for the production of amines by reductive hydride transfer amination, comprising reacting at least one ketone or at least one aldehyde with ammonia, at least one primary amine or at least one secondary amine in the presence of a hydrogen donor as reducing agent and a catalyst, wherein said catalyst is a transition metal complex, further wherein the metal in the transition metal complex catalyst is Rh or Ru.
