Immobilization and chelation of metal complexes with bifunctional phosphine ligands: a solid-state NMR study
Abstract
29 Si CP MAS NMR shows that a transition-metal complex with two bifunctional phosphine ligands such as (CO)2Ni[PPh2(C6H4)SiMe2OEt]2, when attached to a silica surface according to a commonly used procedure, is mainly anchored by just one ligand.
