Copper complexes of dinucleating octa-azamacrocyclic ligands

The synthesis of mono and dinucleating ligands and their copper complexes are described. Three types of dinacleating tetraimine macrocycles have been prepared from 4,7-diaza-2,3;8,9-dibenzodecane-l,10-dione by condensation with the appropriate polyamine; I, large-ring octa-aza macrocycles e.g. the 28—membered ring compound 5,6,7,8,15,16,23,24,25,26,33,34— dodecahydrotetrabenzo(e,m,s,a’) (1,4,11,15,18,22,25) octaaza- cyclooctacosine and related 30- and 36- membered ring compounds; II, the "fused" bis(tetra-azamacrocycle) 5,6,7,8,22,23,24,25-octahydrotetrabenzo (f,f’1,1’) benzo (1,2-b:4,5-b’)- bis(1,4,8,)tetraazacyclotetradecine; III, the "Linked" bis(tetra-azamacrocycle) 5,6,7,8,24,25,26,27-octahydrotetrabenzo (f,f’,1,1)diphenyl(3,4-b:3’,4’-b’)bis(l,4,8,11)tetraazacyclotetradecine. For the type I and III ligands reduction of the imine linkages yielded the related octa-amines. The preparation of copper complexes is described. For many of the neutral copper complexes (formed by deprotonation of anilino nitrogen atoms) a novel synthetic route had to be used to overcome problems associated with the very low solubility of both ligand and complex.
