Cationic iridium(III) complexes bearing a bis(triazole) ancillary ligand.
Three new heteroleptic cationic iridium complexes of the form [Ir(C^N)(btl)](+), where btl = 1,1'-benzyl-4,4'-bi-1H-1,2,3-triazolyl and C^N = 2-phenylpyridine (ppyH) (1), 1-benzyl-4-phenyl-1H-1,2,3-triazole (phtl) (2) or 1-benzyl-4-(2,4-difluorophenyl)-1H-1,2,3-triazole (dFphtl) (3), were synthesized and isolated as their hexafluorophosphate (PF6(-)) salts and fully characterized. The single cr...
متن کاملIridium complexes bearing a PNP ligand, favoring facile C(sp3)-H bond cleavage.
Hydrogen iodide is lost upon reaction of PNP with IrI(3), where PNP = 2,6-bis-(di-t-butylphosphinomethyl)pyridine to give crystallographically characterized Ir(PNP)*(I)(2), which reacts with H(2) to give Ir(PNP)(H)(I)(2). Ir(PNP)(Cl)(3) is relatively inert towards the intramolecular C-H activation of the tert-butyl's of the PNP ligand.
متن کاملPentamethylcyclopentadienyl Halfsandwich Complexes of Rhodium and Iridium Containing l,l'-Ferrocene Dichalcogenido Ligands
A series o f 12 bimetallic complexes Cp*M(L)[(EC5H4)2Fe] (M(L) = Rh(PM e3), Ir(PMe3), Ir(PPh3) and Ir(CN'Bu); E = S, Se, Te) has been synthesized from the dichlorides Cp*M(L)Cl2. The new compounds have been characterized by their 'H, 13C and 31P N M R spectra in solu tion. The mass spectra indicate that the two-electron ligand L is preferentially eliminated upon electron-impact. Oxidation by A...
متن کاملZirconium complexes bearing a tetradentate dipyrrolyl ligand.
Using a tetradentate, dianionic ligand several new zirconium complexes have been prepared. These pyrrolyl compounds, unlike their titanium analogues, are inactive in hydrohydrazination catalysis. However, they are quite stable, and their reactivity with H2NR, where R = Ph, C6H11, and NHPh, is reported here. Two of the complexes were characterized by X-ray diffraction.
متن کاملRhodium and iridium complexes with a new scorpionate phosphane ligand.
A straightforward synthesis of a new hybrid scorpionate ligand [(allyl)2B(CH2PPh2)(Pz)](-) ([A2BPN](-)) is reported. Coordination to rhodium resulted in square-planar complexes [Rh(κ(2)-A2BPN)(L)(L')] [L = L' = (1)/2cod (1,5-cyclooctadiene), CN(t)Bu, CO (6); L = CO, L' = NH3, pyridine, PPh3, PMe3] for which spectroscopic data and the molecular structure of [Rh(κ(2)-A2BPN)(CO)PPh3] (11) indicate...
