    • note
    • Recently, van Leeuwen and Werner independently reported on neutral carbene complexes with bisphosphines, which show a very low ROMP activity. Addition of trimethylsilyl triflate to these neutral complexes leads to formation of new species, which were not characterized. The reports are incoherent concerning the ROMP activity of these species: (a) Werner, H.; Jung, S.; Gonzáles-Herrero, P.; Ilg, K.; Wolf, J. Eur. J. Inorg. Chem. 2001, 1957.

    • It should be noted that a high purity of the cycloolefin substrates is crucial to achieve high ROMP rates at these low catalyst loadings.
