In this study, density functional theory (DFT) calculations were performed to explore the reaction mechanism for formation of a silver-formimidamide intermediate complex in synthesis pathway novel cyclometallated iridium(III) bearing pyridine-formimidamide ancillary ligand. The purpose study is provide detailed explanation how cyclic carbene ligand (2-(4-methylbenzyl)-1H-1,2,4-triazol-1-yl)pyridine, MBpyta converted into acyclic (E)-N-cyano-N-(4-methylbenzyl)-N'-(pyridin-2-yl) formimidamide,...
In this study, [Ir(2,4-F2ppy)2(2-(1,2,4-triazol-1-yl)pyridine>)]PF6 (C1), [Ir(2,4-F2ppy)2(2-(2-(4-dimethylbenzyl)-1,2,4-triazol-1-yl)pyridine)]PF6 (C2) and [Ir(2,4-F2ppy)2(2(2-hexyl-1,2,4-triazol-1-yl)pyridine)]PF6 (C3) complexes were successfully synthesised by refluxing the mixture of dichloro-bridged iridium(III) dimer, [Ir(2,4-F2ppy)2(μ-Cl)]2 corresponding triazolium salt containing N-heterocyclic carbene (NHC) as ancillary ligands. 1H NMR all display well-resolved signals between...
A cationic complex of iridium(III), [Ir(2,4-F2ppy)2(F2bpyta)]PF6 utilizing 1,2,4-triazolepyridyl as an anchillary ligand modified with a 2,6-difluorobenzyl substituent was synthesized and characterized. The aromatic signals pyridyltriazole phenylpyridine proton were detected in the 1H-NMR spectrum between 10.00 7.00 ppm. Only one singlet peak at 8.46 ppm H(8) shifted to upfield, demonstrating that C5 coordinated central iridium metal. bands exhibited range 1555–1431 cm–1 IR because C=C C=N...
The cationic complex [Ir(bFppy)2(pyim)]+ (bFppy = 2-(2-butoxy-4-fluorophenyl)pyridine and pyim 2-(1H-Imidazol-2-yl)pyridine) was excellently prepared between 2-(1H-Imidazol-2-yl)pyridine chloro-bridged iridium(III) dimer via reflux reaction. Butoxy functional group fluorine atom were added to the phenyl ring of 2-phenylpyridine at positions 2 4 respectively, as cyclometalating ligand. characterized by spectroscopic methods: FTIR, NMR, LCMS UV-Vis absorption. presence two sharp peaks 1256...
