Abstract
A synthetic method leading to the isolation of ruthenium-based olefin metathesis catalysts relies on the cross metathesis reaction between (L.sub.1)Ru(L.sub.2)(3-phenylindenylid-1-ene)Cl.sub.2 (where L.sub.1 and L.sub.2 can be two-electron donors) and an olefin. This method leads to the isolation of numerous ruthenium olefin metathesis catalysts.
