ABSTRACT:
The invention relates to 3-amino-4-aminomethyl-pyrrolidines which contain, in the 1-position of the heterocyclic ring, organic radicals as substituents, and in which also the H-atom in the 2-position of the heterocyclic ring can be substituted by an organic radical. The invention also relates to the preparation of these pyrrolidines by catalytic hydrogenation of the corresponding 3-amino-4-cyano-3-pyrrolines. Hydrogenation is preferably performed in the presence of NH.sub.3. The amines according to the invention are suitable as curing agents for epoxide resins, as reactants for isocyanates, and as starting substances for polyamides.
