Four-membered C^N chelation in main-group organometallic chemistry

Abstract

Main-group organometallic compounds containing four membered C^N chelating rings are being studied because of the interest in harnessing the enhanced reactivity of such compounds facilitated by the release of steric...

Integrating Prior Chemical Knowledge into the Graph Transformer Network to Predict the Stability Constants of Chelating Agents and Metal Ions

“…For the construction of A 2 , we collated various possible scenarios of metal ions and ligands forming coordination bonds from extensive literature reviews. − As illustrated in Figure , these scenarios include interactions with nitrogen atoms in macrocyclic compounds, singly bound to oxygen atoms in carboxyl and phosphate groups, nitrogen atoms on amides, oxygen atoms of hydroxylamines on N -hydroxypyridones, singly bound to oxygen atoms in pyridine carboxylic acid group, and oxygen atoms in hydroxyl-substituted quinolines, pyridones, and pyranones.…”

Fabrication of metal–organic salts with heterogeneous conformations of a ligand as dual-functional urease and nitrification inhibitors

“…Researchers have been studying organometallic compounds (OMCs) for more than 100 years, and various OMCs have been widely used in various fields. [9][10][11][12] Cu-based OMCs have been extensively studied because of their good UI effect. 13,14 Niu et al prepared and characterized three Cu-based OMCs and tested the UI effect of different concentrations of Cu-based OMCs and substrate urea cultured for three hours with the phenol red method.…”

Stabilization of unusual discrete diorganotin carboxylates using the intramolecular coordination approach: synthesis, structure, TD-DFT, and Hirshfeld surface analyses

“…25–27 Recently, there has been increased scientific interest in investigating the intramolecular coordination of organometallic complexes. 28…”

“…[25][26][27] Recently, there has been increased scientific interest in investigating the intramolecular coordination of organometallic complexes. 28 In our previous reports, several new organotin-containing structural motifs have been developed employing the intramolecular N -Sn coordination approach. In the case of the previously reported hexanuclear drum [RSn(m-O 2 CPh)] 6 (R = 2phenylazophenyl), it was observed that in addition to the electronic factor, the steric factor was also found to be prominent, where no N -Sn coordination was retained in the structure.…”
