WebFeb 1, 2024 · Low-denticity ligands such as β-keto acids offer the best selectivities, but speciation is an issue as other polydentate ligands such as pyrophosphate may complete the coordination sphere. WebGeneral Properties. Like CO, phosphines are dative, L-type ligands that formally contribute two electrons to the metal center. Unlike CO, most phosphines are not small enough to form more than four bonds to a single metal center (and for large R, the number is even smaller).
