Zusammenfassung:Process for the preparation of 1:1 metal complexes of azines of the formula 1) in which R1 is an H atom or an alkyl or aryl group, is an isocyclic or heterocyclic radical with a hydroxyl or mercapto group adjacent to the azonethine group, Y' is the radical of a methylene-active compound or of an arylor beteroaryl-amine and the ring A can have substituents which do not confer solubility in water, which comprises heating hydrazone of the formula 2) with an isoindolinone of the formula 3) in which R1, Q, A and Y' are as defined, in the presence of a metal donor, in a polar organic solvent.
