Slow Migration of a Phosphorus Ligand between Two Metal Centers

Slow Migration of a Phosphorus Ligand between Two Metal Centers

Slow dance: Long believed to be impossible, migration of a phosphorus ligand via a bridging intermediate is observed between two metal centers in a diiron complex containing an asymmetric bridging ligand. This process occurs in a similar fashion to the migration of carbonyl ligands but at a rate slo...

Zusammenfassung:Slow dance: Long believed to be impossible, migration of a phosphorus ligand via a bridging intermediate is observed between two metal centers in a diiron complex containing an asymmetric bridging ligand. This process occurs in a similar fashion to the migration of carbonyl ligands but at a rate slow enough to be studied by NMR spectroscopy.
