Abstract:	An exptl. comparison of the gas-phase reactivity of the 14-electron reactive intermediates produced by phosphine dissocn. from the first- and second-generation ruthenium metathesis catalysts, (L)Cl2Ru=CHR (L = PCy3 or NHC), supports Grubbs's contention that the second-generation catalysts show hundred-fold higher phenomenol. activity despite a slower phosphine dissocn. because of a much more favorable partitioning of the 14-electron active species towards product-forming steps. The gas-phase study finds, in ring-opening metathesis of norbornene as well as acyclic metathesis of Et vinyl ether, that the first-generation systems display evidence for a higher barrier above that for phosphine dissocn.; the second-generation systems, on the other hand, behave as if there is no significantly higher barrier.
