Synthesis of 1,2-Bis(1,4,7,10-tetra-azadodecanyl)ethane, a Double-ring Fully Saturated Macrocycle containing 12-Membered Tetra-aza Subunits

Article abstract of DOI:10.1039/c39840000998

The title compound, a fully saturated bimacrocycle (1), has been obtained through a procedure involving the protection of all but one of the amino nitrogen atoms of each tetra-aza ring which are then bridged by an ethylenic segment; (1) behaves as a dinucleating ligand, forming a dicopper(II) complex in which there is a weak ferromagnetic interaction between the metal atoms.
