Abstract

The kinetics of intermolecular alkene-alkyne (ene-yne) metathesis promoted by the first generation Grubbs catalyst (Cy₃P)₂Cl ₂Ru=CHPh (1) were investigated. The dissociated tricyclohexylphosphine plays an important kinetic role during the initial exchange with the terminal alkyne, resulting in a half-order rate dependence on 1 and first-order dependence on the alkyne.
