In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. [1] . The compounds are structurally related to acid anhydrides, although imides are more resistant to hydrolysis. In terms of commercial applications, imides are best known as components of high-strength polymers, called polyimides.

In coordination chemistry and organometallic chemistry, transition metal imido complexes is a coordination compound containing an imido ligand. Imido ligands can be terminal or bridging ligands. The parent imido ligand has the formula NH, but most imido ligands have alkyl or aryl groups in place of H.

2015年3月31日 · Imido ligands, also referred to as imides or nitrenes, are a common ligands in high oxidation state transition metal chemistry. A metal imido has the general form M=NR where there is a double bond between the metal center and the nitrogen atom.

2021年7月28日 · Metal−nitrogen formally multiple bonded complexes, i. e. nitrenes, imidyls, and imido ligands, are key intermediates in organic catalysis and group transfer chemistry.

2020年3月15日 · In this review, we focus on the reactivity of mononuclear group 4–6 metal complexes having terminal imido ligands, and summarize their stoichiometric and catalytic organic transformations initiated by cycloaddition of the M N bond with unsaturated organic molecules. 2. Stoichiometric reactions. 2.1. Cycloaddition reactions.

Imidyl and nitrene metal species play an important role in the N-functionalisation of unreactive C–H bonds as well as the aziridination of olefines. We report on the synthesis of the trigonal imido iron complexes [Fe(NMes)L2]0,− (L = –N{Dipp}SiMe3); ...

2024年3月27日 · Terminal imido complexes containing metal–nitrogen multiple bonds have been widely used in organometallic chemistry and homogeneous catalysis. The role of terminal imido ligands spans from reactive...

2024年4月4日 · Terminal imido complexes, containing metal-nitrogen multiple bonds, have been widely used in organometallic chemistry and homogeneous catalysis. The role of terminal imido ligands span from reactive site to spectator motif, largely depending on the nature of the metal center and its specific coordination sphere.

2024年10月23日 · The nature of M=N bond is highly depended on the metal centres and their d-electron configuration, with late transition metal (TM) imido complexes exhibiting contrasting features when compared to their early TM analogues.
