Strongly Binding Ligands Cause the Carbene Fragment to be Lost as a Phosphorus Ylide Isocyanide ligand binds to ruthenium and sweeps away the carbene fragment The rapid loss of carbenic activity stops metathesis with this first generation Grubbs complex “Isocyanide-Promoted Ylidene Transfer to Phosphorus: Rearrangement in the First Generation Grubbs Complex” Galan, B.
