Abstract
A gas-phase comparison of intrinsic olefin metathesis rates for (carbene)ru thenium complexes by means of electrospray-ionization tandem mass spectrome try reveals a reversal of the reactivity trends observed in solution. The s olution-phase ordering of reactivity is accordingly attributed to a more fa vorable pre-ecquilibrium, producing the metathesis-active species in the ca se of the Hofmann- and Werner-type complexes relative to those of the Grubb s type.
