    摘要： Nitrogen-containing substituents of aliphatic or aromatic compounds can be reduced by treatment with a reagent comprising (i) at least one complex of a transition metal of group 4 or 5 with a multidentate or unidentate organic or inorganic ligand and (ii) a reducing agent. The reaction is conducted optionally in the presence of an aliphatic or aromatic amine, and/or in the presence of an inert organic solvent.

    摘要： The invention relates to bis(3-cyano-3,5,5-trimethylcyclohexylidene)-azine (=IPN-azine), a method of its preparation by reacting 1,3,3-trimethyl-5-oxocyclohexane carbonitrile (=IPN) with a source for hydrazine in a molar ratio of essentially 2 to 1 in the presence of a solvent and to a method for the further processing of the IPN-azine to 3-(aminomethyl)-3,5,5-trimethylcyclohexyl amine (isophorone diamine=IPDA) by means of a hydrogenating azine splitting with hydrogen in the presence of an organic solvent, ammonia and of a catalytic system from the series (a) of a cobalt- or nickel-containing Raney catalyst and of a cocatalyst from the series of salts of the elements aluminum, cobalt, nickel, yttrium, lanthanum, cerium, Ru, Rh, Pd, Ir and Pt or of carrier-supported noble metals from the series Ru, Rh, Pd, Ir, Pt or b) of a carrier-supported Ru-, Pd- or Pt catalyst at a pressure of 3 to 30 MPa and a temperature of 50.degree. to 150.degree. C. The method of the invention concerning IPN-azine makes it possible to obtain IPDA from IPN in high yield and purity and avoids disadvantages of the previously known reductive amination of IPN.
