Our results indicate that to cleave effectively an amide bond, it is essential for a metal centre to bind to the amide bond and the metal centre is of sufficient Lewis acidity. In a previous review of metal amide coordination chemistry, Sigel and Martin provided a summary of the structure and stability of metal amide complexes with a strong emphasis on metal complexes containing proteins and peptides. Experimental stability constant data, kinetic information, spectroscopic (IR, NMR, ESR, and electronic) measurements, circular dichroism spectroscopy and some data from X-ray crystal structures were used to examine amide metal interactions in these polydentate ligands. The coordination of metal ions to the free acrylamide or to the amide residue of an acrylamide adduct may play a catalytic role in prompting biochemical reactions, that either the vinylic group or the amide residue can undergo. It is clear that metal atoms coordinated to an organic substrate affect the reactivity of the substrate.
The structures of complexes between amides and metal ions were examined by FAB mass spectrometry and collision-induced dissociation (CID). Zn2+ was coordinated by the amide carbonyl oxygen atom of N-tetradecylacetamide (1). In contrast, Ca2+ and Mg2+ were coordinated by the amide group of 1 in both the keto and enol forms.

"Ammine" is spelled this way due to historical reasons; in contrast, alkyl or aryl bearing ligands are spelt with a single "m". Almost all metal ions bind ammonia as a ligand, but the most prevalent examples of ammine complexes are for Cr, Co, Ni, Cu as well as several platinum group metals.
