1,n-cyclohexanediamines (n=2, 3, 4) of general formula (I), wherein one of the radicals R<1> to R<3> is an amino group and the two others mean hydrogen, are produced from the corresponding cyclohexanediols and ammonia in the presence of a catalyst containing cobalt, at 100-350 DEG C and 50-300 bar. The compounds that can be produced according to the invention are structural elements for polymers, especially polyamides, polyimides, polyurea or polyurethanes, and ligands for cytostatically effective transition metal complexes. |
