Surprisingly similar reactions in the gas phase and in solution [Eq. (a)]: The ion 1 obtained by electrospray ionization behaves in the gas phase analogously to the corresponding complex [RuCl<sub>2</sub> (=CHPh)(PCy<sub>3</sub> )<sub>2</sub> ] in solution. Measured relative rates for ring-opening metathesis are interpreted under the assumption of an intramolecular π complex, which leads to an estimation of the equilibrium constant for π complexation.
