Abstract
In the presence of ammonia or amine some azomethines were catalytically hydrogenated under high hydrogen pressure to give two kinds of amines according to the equation : [chemical formula] In the pathway of this hydrogenation reaction, the first stage preceding hydrogenation was proposed to be the replacement reaction of amine residue of azomethine by that of ammonia of amine. This was demonstrated using N-benzylidene-4-sulfonamidobenzylamine as azomethine.
