ABSTRACT:
Macrocyclic imines useful as complexing agents for ionic metal compounds characterized by a macrocyclic ring or rings of carbon and hetero-atoms totaling 14-60 ring atoms, at least one hetero-atom being nitrogen and the remainder being oxygen, each hetero-atom in the ring being separated from adjoining hetero-atoms by links of 2 or 3 carbon atoms. The macrocyclic ring or rings are fused to 1-4 carbocyclic rings. The macrocyclic rings or substituted derivatives of them can be monocyclic, bicyclic, or bridged by a carbon, or carbon-hetero-atom chain.
