2. One may argue that observation of the cyclopropanation channel could also be achieved by sequential loss of the olefin and carbene moieties. However, quantitative CID determination for this path agrees well with DFT calculations, thus confirming our assignment: Unpublished results.

8. We have estimated the probability of collisions under conditions tested as described in the literature: Armentrout, P. B. The Encyclopedia of Mass Spectrometry; Elsevier: Amsterdam, 2003; Vol. 1, pp 451-455. As obtained using a total cross-section with the p-(trifluoromethyl)benzylidene olefin complex, single collision should occur for approximately 20% of parent molecules and double collision for approximately 5%, with negligible contribution from triple collisions.
