Metal amide coordination

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. Written by internationally recognised leaders in the field, Metal Amide Chemistry is the authoritative survey of this important class of compounds, the first since Lappert and Power’s 1980 book “Metal and Metalloid Amides.” An introduction to the topic is followed by in-depth discussions of the amide compounds of: alkali metals alkaline earth metals zinc, cadmium and mercury the The dark green Fe[N(SiMe 3) 2] 2 complex exists in two forms depending on its physical state. At room temperature the compound is a monomeric liquid with two-coordinate Fe centers possessing S 4 symmetry, in the solid state it forms a dimer with trigonal planar iron centers and bridging amido groups.

Coordination occurs through the carbonyl oxygen of the amide group. A literature review of structures of amide complexes of metal ions was carried out Metal amides (systematic name metal azanides) are a class of coordination compounds composed of a metal center with amide ligands of the form NR 2 −.Amide ligands have two electron pairs available for bonding.

Intuitively, we should expect the acidity of amines, alcohols, and thiols to increase upon coordination, because removal of electron density from nitrogen and oxygen through coordination makes these atoms more electrophilic.

Together they form a unique fingerprint. Enzymatic hydrolysis … In this Minireview, the fate of amine–boranes upon coordination to a metal center is discussed with a particular emphasis on B H activation pathways. We focus on the few cases in which coordination of the resulting dehydrogenated product could be achieved, which includes the coordination of aminoborane, the simplest unit resulting from dihydrogen release of ammonia–borane.
