The bicyclic amine I was prepd. in 30% yield by condensation of tetra-Et 1,1,2,2-ethanetetracarboxylate with 1,4,8,11-tetraazaundecane in refluxing EtOH for 2 days and formed a 1:2 complex with Cu2+ in aq. soln. The 2Cu2+-I complex showed weak metal-metal interaction and was easily oxidized to the trivalent state by 2 consecutive one-electron steps sepd. by 110 mV.

Abstract
The bicyclic amine I was prepd. in 30% yield by condensation of tetra-Et 1,1,2,2-ethanetetracarboxylate with 1,4,8,11-tetraazaundecane in refluxing EtOH for 2 days and formed a 1:2 complex with Cu2+ in aq. soln. The 2Cu2+-I complex showed weak metal-metal interaction and was easily oxidized to the trivalent state by 2 consecutive one-electron steps sepd. by 110 mV.File in questo prodotto:
