Diarylplatinum(II) Compounds as Versatile Metallating Agents in the Synthesis of Cyclometallated Platinum Compounds with N-Donor Ligands

Inorganics, 2014
This review deals with the reactions of diarylplatinum(II) complexes with N-donor ligands to produce a variety of cycloplatinated compounds including endo-five-, endo-seven-, endo-six- or exo-five-membered platinacycles.

Chlorido-pentamethylcyclopentadienyl-[2-(2-pyridyl-кN)-ferrocenyl-кC]-iridium(III)

Molbank
Treatment of 2-pyridyl-ferrocene wit [Cp*IrCl2]2 in the presence of NaOAc produces the title compound Cp*ClIr[(C5H3C5H4N-кN,кC)Fe(C5H5)] (2) in low yield. A crystal structure determination shows the (SpSIr/RpRIr)-2 enantiomeric pair of diastereomers.

Synthesis and Characterization of Iridium(III) Complexes containing (ppy)2Ir-unit and Nitrogen based Donor Ligands [PDF]

OUSL Journal
The treatment of 4-dimethylamino pyridine (L1) with 0.5 equivalent of [Ir(ppy)2(μ-Cl)]2 afforded the neutral yellow complex [Ir(ppy)2(L1)Cl] (1) in 81% yield (ppyH = 2-phenylpyridine).

Platinum-carbon bond formation by cyclometallation and oxidative addition reactivity of organoplatinum compounds

, 1988
The work described in this thesis stems from the observation that a pyrazolyl group in Me2Pt(HCpz3) umdergoes a Cyclometallation reaction when heated in neat pyridine, giving rise to a NC- coordination mode, which is uncommon for flexible carbon bridged ...

Recent Findings in Cyclometallation of Meta-Substituted Aryl Ligands by Platinum Group Metal Complexes by Caryl-R Bond Activation (R=H, CR3,SiR3) [PDF]

, 1998
Cyclometallation of aryl ligands with two donor substituents in the meta positions occurs through Caryl-R bond activation. This procedure, which is outlined below (Y=N-, P- and S-donor ligands; R=H, CR3, SiR3), has been used for the preparation of ...

Crystal structure of {3-[3,5-bis(2,6-dimethylphenyl)-1,2-phenylene]-1-(2,6,2′′,6′′-tetramethyl-1,1′:3′,1′′-terphenyl-5′-yl)imidazol-2-ylidene}chlorido(η6-p-cymene)ruthenium(II) benzene disolvate

Acta Crystallographica Section E, 2014
The title compound, [Ru(C47H43N2)Cl(C10H14)]·2C6H6, crystallized with two independent molecules of benzene. One of the N-aryl moieties of the N-heterocyclic carbene (NHC) ligand underwent cyclometallation to form a five-membered ruthenacycle. The complex

Racemic (RSC,SRS)-(2-{[1-allyloxycarbonyl-3-(methylsulfanyl)propyl]iminomethyl}phenyl-κ3S,N,C1)chloridoplatinum(II)

Acta Crystallographica Section E, 2009
The title compound, [Pt(C15H18NO2S)Cl], was obtained by the cyclometallation reaction of cis-bis(benzonitrile)dichloridoplatinum(II) with N-benzylidene-l-methionine allyl ester in refluxing toluene. The PtII atom has a square-planar geometry and is tetra-

Facile cyclometallation of a mesitylsilylene: synthesis and preliminary catalytic activity of iridium(iii) and iridium(v) iridasilacyclopentenes.

Chemical Communications, 2017
Reactions of the mesityl-amidinato-silylene Si(tBu2bzam)Mes (1; tBu2bzam = N,N'-bis(tert-butyl)benzamidinato; Mes = mesityl) with three different iridium precursors led, at room temperature, to two iridium(iii) and one iridium(v) complexes featuring one (

Synergistic Mechanism Between Ir–Phosphinito Catalyst and HFIP Enables Asymmetric Hydrogenation of Ketones Under Acidic Conditions

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
A cooperative mechanism between a phosphinito Ir complex and HFIP provides a low‐energy pathway for hydrogen activation. This allowed the development of a highly efficient catalytic system for the hydrogenation of ketones that operates under acidic conditions, enabling the reduction of substrates containing phenols and carboxylic acids with no added ...
