Dichloro(tricyclohexylphosphine)[(tricyclohexylphosphoranyl)methylidene]ruthenium(II) tetrafluoroborate

Cationic 4-coordinate catalyst is considered “pre-activated” because no ligand dissociation is required for formation of the active catalytic species. Has reactivity profile similar to Grubbs Catalyst^? 1^st Generation but is active at much lower temperatures (below 0 °C).
