摘要：1,n-cyclohexanediamines (n=2, 3, 4) of general formula (I), wherein one of theradicals Rto Ris an amino group and the two others mean hydrogen, are produced fromthe corresponding cyclohexanediols and ammonia in the presence of a catalyst containingcobalt, at 100° to 350° C. and 50 to 300 bar. The compounds that can be producedaccording to the invention are structural elements for polymers, especially polyamides,polyimides, polyurea or polyurethanes, and ligands for cytostatically effective transitionmetal complexes.
