Process for the preparation of 1:1 metal complexes of azines of the formula <IMAGE> (1) in which R1 is an H atom or an alkyl or aryl group, R2 is an isocyclic or heterocyclic radical with a hydroxyl or mercapto group adjacent to the azomethine group, Y' is the radical of a methylene-active compound or of an aryl-or heteroaryl-amine and the ring A can have substituents which do not confer solubility in water, which comprises heating a hydrazone of the formula <IMAGE> (2) with an isoindolinone of the formula <IMAGE> (3) in which R1, R2, A and Y' are as defined, in the presence of a metal donor, in a polar organic solvent.
