WebAug 28, 2024 · Phosphine complexes are most commonly made through ligand substitution processes—the exchange of one ligand for another on a metal center. One interesting method utilizes tertiary N-oxides to essentially “oxidize off” a CO ligand, leaving behind an open coordination site that may be filled by a phosphine. WebDec 16, 2009 · Ligands, Metals, Phosphorus Abstract The bonding between phosphorus ligands X = PCl 3, PF 3, P (OCH 3) 3, PH 3, PH 2 CH 3, PH (CH 3) 2, P (CH 3) 3 and the metal-containing fragments [Ni (CO) 3 ], [Mo (CO) 5 ], and [Fe (CO) 4] have been studied by Natural Orbitals for Chemical Valence (NOCV).
WebMar 5, 2003 · We conclude that the enhanced reactivity of MCRred1 is due to the replacement of a relatively exchange-inert thiol ligand in MCRox1 with a weakly coordinating upper axial ligand in red1 that can be easily replaced by incoming ligands.
