The synthesis and polymerization of 2,3-diazanorborn-5-enes are reported. Reaction of 2,3-diazanorborn-5-ene derivatives 6–9 with molybdenum based initiators 1–3 leads, in most cases to ring opening metathesis polymerization. By contrast, monomers 6–9 are not polymerized by ruthenium based initiator 4. The polymers were characterized by NMR, GPC and MALDI-TOF mass spectrometry and were found to have narrow molecular weight distributions and to show a resonance attributable to a propagating alkylidene in the 1H NMR spectrum.
