| 摘要 |
The invention concerns a process for the reduction of groups containing unsaturated C,C-, C,N-,N,N-,N,O- bonds, especially of NO2-,NO-,NOH-,NR-,CN-,N3-,N2-groups or C=C or C-halogen- or acyl groups with hydrogen on MPc or with a suitable reduction agent on [MPc](-), whereby a platinum metal-phthalocyanine is used as the catalyst. It is possible that by the reversible change (control) of the oxidation phase z of the platinum metal from z>/=2 to z</=1 using the same MPc complex, basically different reductions can be selectively catalysed. Thus the invention concerns a process for selective reduction using platinum metal-phthalocyanine catalysts with reaction specificity in three different reaction patterns. The inventive process is suitable, especially for the synthesis of alpha -phenylalkylamines, benzylalkylamines, N-alkyl-amino carboxylic acids, alpha -hydroxycarboxylic acids, peptides, N-heterocyclic compounds as well as generally in the field of pharmaceutical, herbicide and insecticide production. |
