Abstract

The RuIV-based transition metal catalysts [Ru(η3:η3-C10H16)Cl2(PPh3)] (1), [Ru(η3:η3-C10H16)Cl2(PCy3)] (2), and [Ru(η3:η3-C10H16)(CF3COO)2(PPh3)] (3) have been synthesized and investigated for their use as initiators in the thermally and photo-initiated ring-opening metathesis polymerization (photo-ROMP) of norborn-2-ene (NBE). Compounds 1 and 3 display significant photo-ROMP activity with NBE whereas compound 2, although active in the ROMP of NBE, shows virtually no latency at all. The results are discussed with respect to the structural features of the novel catalysts.
