F. Bellouard et al., Synthesis of a ferrocene-linked biscyclam: a new type of redox active bismacrocyclic ligand, NEW J CHEM, 23(12), 1999, pp. 1133-1135
Making use of a selective mono-N-alkylation method for tetraazamacrocycles,
through the cyclam phosphoryl intermediate, the synthesis of a new redox-a
ctive ferrocene-bridged biscyclam is described; strong electrostatic intera
ctions in the binuclear metal complexes (M = Ni, Cu) are electrochemically
detected.
