    • Although the symmetry for 8 does not allow measurement of the site epimerization rate, we assume that inversion at zirconium also accompanies olefin dissociation for this cation.

    • 2 (15) (see Supporting Information). Unfortunately, the amount of 15 that was isolated precluded further study. The precise mechanism of the reaction forming 15 is unknown at this time.

    • 1H NMR spectrum of the olefin complex can be observed: a multiplet at 8.4 ppm and a matching set of doublets at -0.4 and 2.8 ppm. Upon warming to -50°C, all peaks corresponding to 17 disappear, but the course of the decomposition of the proposed olefin complex is not easily followed.
