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.

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.

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.

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...

Building on these earlier works, in this Article, we show that the imido ligand in a low-coordinate high-spin bis (carbene)borate Fe (II) complex is able to access previously unknown reaction pathways, ultimately leading to new catalytic transformations.

2024年1月12日 · Here we present the isolation and characterization of a rare, trigonal imido cobalt(III) complex, which bears a rather long cobalt-imido bond. It can cleanly cleave strong C-H bonds with a bond dissocn. energy of up to 92 kcal mol-1 in an intermol. fashion, unprecedented for imido cobalt complexes.

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.
