Good for a ROMP: Initiators 1 and 2, which both contain an unsymmetric, chiral N-heterocyclic carbene (NHC) ligand, mediate the alternating copolymerization of norborn-2-ene with other cyclic olefins including cyclopentene and cyclooctene. The selectivity of the copolymerization is explained by the steric interaction of the growing polymer chain with the 1-phenylethyl substituent and the nitrogen atom of the NHC ligand.
