Amide and Ketimide Metal Complexes

Abstract

In the present article, we will provide an overview of amide and ketimide metal complexes with an emphasis on the recent developments of the field since 2000. The article will be divided into two sections: a section on metal amide complexes and another section on metal ketimide complexes, with both discussing the recent developments in the synthesis, characterization, reactivity, and applications of representative metal complexes and their closely related derivatives. The amide section is organized as follows: a preliminary section defining the scope of amide ligands and their coordination modes, followed by the synthesis and structure of metal amide complexes subdivided based on the metal group. In each of the subsections, the content is organized according to the hapticity of the amide ligand to a single metal center, i.e., monodentate, bidentate, and polydentate amide complexes. The amide section then contains a discussion of the representative reactivity and applications of metal amide complexes, and is closed off with a summary of recent advancements and provides perspectives about the future directions of the field. The ketimide section is organized similarly, proceeding in chronological order across the periodic table starting with the alkali and alkaline earth metals, moving to group 3 and f-block metals, followed by the rest of the transition metals sectioned by group number and ending with group 14. This section is concluded with a brief synopsis of all literature reviewed in this article, as well as suggestions for future directions.
