A new cyclam based first generation metallodendrimer with nickel centres on the periphery as well as at the core was synthesized by reacting a novel tetrakis(salicylaldimine) cyclam ligand with nickel acetate. The trinuclear complex was evaluated as a catalyst precursor in the vinyl polymerization of norbornene using methylaluminoxane as co-catalyst. The activity of this cyclam-based complex was compared with that of first generation DAB-PPI-salicylaldimine and DAB-PPI-pyridine-imine complexes (DAB = diaminobutane, PPI = polypropyleneimine). The cyclam based complex was found to have superior activity than both the DAB-PPI analogues as well as analogous mononuclear complexes.
