Ligand design in early transition metal chemistry has focussed
recently on amide chemistry. The availability of two substituent positions
at the amido N-donor atom allows its integration into ligand systems of
both podand and macrocyclic topology. Amido functions may be combined with
other donor functionalities which possess a different formal charge and
chemical hardness and, more generally, a different thermodynamic and
kinetic stability of their interaction with the metal centre. Early
transition metal complexes containing polydentate amido-donor ligands not
only display unprecedented patterns of reactivity but are the focus of
recent developments in olefin polymerization catalysis.
