ABSTRACT:
The invention concerns a process for the reduction of groups containing unsaturated C,C--, C,N--,N,N--,N,O-- bonds, especially of NO.sub.2 --,NO--,NOH--,NR--,CN--,N.sub.3 --,N.sub.2 -groups or C.dbd.C or C-halogen- or acyl groups with hydrogen on MPc or with a suitable reduction agent on [MPc].sup..crclbar., 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.gtoreq.2 to z.ltoreq.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.
