WebApr 8, 2024 · The two-electron oxidative addition of aryl and alkyl halides to a reduced iron dinitrogen complex with a strong-field tridentate pincer ligand has been demonstrated. Addition of iodobenzene or bromobenzene to (3,5-Me2MesCNC)Fe(N2)2 (3,5-Me2MesCNC = 2,6-(2,4,6-Me-C6H2-imidazol-2-ylidene)2-3,5-Me2-pyridine) resulted in rapid oxidative … WebJan 25, 2024 · The Chirik lab explores sustainable chemistry by investigating the use of iron to build new molecules. In this particular research, the iron “persuades” the monomers to click together to make the polymer of squares. Normally, monomers connect to form a polymer — which is simply a repeating unit of monomers — through an S-shaped ...
