Photochemical isomerization of metal ethene to metal vinyl hydride complexes: a matrix-isolation and solution NMR study was written by Bell, Tanachat W.;Haddleton, David M.;McCamley, Andrew;Partridge, Martin G.;Perutz, Robin N.;Willner, Helge. And the article was included in Journal of the American Chemical Society in 1990.Formula: C8H16Cl2Ir2 This article mentions the following:

CpRh(PMe₃)(C₂H₄) (I), CpIr(PMe₃)(C₂H₄) (II), and CpIr(C₂H₄)₂ (III) (Cp = η⁵-cyclopentadienyl) are isomerized on photolysis in argon matrixes at 12-20 K to metal vinyl hydride complexes CpM(L)(C₂H₃)H (L = PMe₃, C₂H₄). The products are identified by their characteristic metal hydride and vinyl group vibrations in the IR spectra and by the effect of ²H-labeling experiments The same products were generated by photolysis of I and III in a frozen toluene solution at 77 K or a cold toluene solution of II and characterized by ¹H, ¹³C, and ³¹P NMR. The vinyl hydride complexes exhibit a wide range of thermal stabilities isomerizing to their precursors at the following temperatures: CpRh(PMe₃)(C₂H₃)H at âˆ?53 K, CpIr(PMe₃)(C₂H₃)H at âˆ?93 K, CpIr(C₂H₄)(C₂H₃)H at âˆ?73 K. Photolysis of I in toluene solution at 188 K generates a mixture of CpRh(PMe₃)(C₂H₃)H and isomers of CpRh(PMe₃)(tolyl)H; at higher temperatures only insertion into toluene C-H bonds is observed Secondary photolysis of CpIr(C₂H₄)(C₂H₃)H in Ar matrixes causes ethene loss and formation of a product identified as the vinylidene complex CpIr(C:CH₂)H₂. Photolysis of III in CO and N₂ matrixes leads to substitution products CpIr(C₂H₄)L (L = CO, N₂), CpIr(CO)(C₂H₃)H, and CpIr(C₂H₄)(C₂H₃)H. Photolysis of I in CO matrixes generates CpRh(PMe₃)CO only; use of N₂ matrixes results in formation of CpRh(PMe₃)N₂ and CpRh(PMe₃)(C₂H₃)H. The photoproducts of II in CO matrixes are CpIr(PMe₃)(C₂H₃)H and CpIr(PMe₃)CO.

A series of carbonyl, olefin, alkyne, hydrido, and vinyl iridium complexes containing bulky bifunctional phosphines iPr₂PCH₂X as ligands was written by Steinert, Paul;Werner, Helmut. And the article was included in Chemische Berichte/Recueil in 1997.Product Details of 39722-81-1 This article mentions the following:

Etheneiridium(I) complexes trans-[IrCl(C₂H₄)L₂] [L = iPr₂PCH₂CO₂Me, iPr₂PCH₂CO₂Et, iPr₂P(CH₂)₃NMe₂] were prepared either from [IrClL₂] or [IrCl(C₂H₄)₂]₂ as starting materials. The corresponding carbonyl derivatives trans-[IrCl(CO)L₂] were obtained along similar routes. Photolysis of trans-[IrCl(C₂H₄)L₂] (L = iPr₂PCH₂CO₂Me, iPr₂PCH₂CO₂Et) leads, by intramol. C-H activation, to the formation of octahedral [IrHCl(CH:CH₂)(κ-L)(κ²-L)], which are highly fluxional in solution The crystal structure of [IrHCl(CH:CH₂)(κ-L)(κ²-L)] (L = iPr₂PCH₂CO₂Me) is reported. Carbonyl hydrido vinyl complexes are accessible either from [IrHCl(CH:CH₂)(κ-L)(κ²-L)] and CO, or from trans-[IrCl(C₂H₄)L₂] (L = iPr₂PCH₂CO₂Me) and HCCCHPhOH, resp. Treatment of [IrClL₂] or the corresponding dihydrido compound [IrH₂ClL₂] with CH₂:CHCOMe or CH₂:CHCO₂Me also yields Ir(III) complexes [IrHCl(CH:CHX)L₂] (X = COMe, CO₂Me), in which instead of the CO function of the phosphinyl ester the CO group of the vinylic moiety is coordinated to the metal. The reaction of [IrHCl(CH:CH₂)(κ-L)(κ²-L)] (L = iPr₂PCH₂CO₂Me) with HCCR (R = Ph, CO₂Me) affords the structurally related alkynyl hydrido Ir(III) compounds [IrHCl(CCR)(κ-L)(κ²-L)], while from [IrHCl(CH:CH₂)(κ-L)(κ²-L)] (L = iPr₂PCH₂CO₂Me) and internal alkynes RCCR the Ir(I) complexes trans-[IrCl(RCCR)L₂] (R = Ph, CO₂Me) were obtained. Stepwise treatment of trans-[IrCl(CO)L₂] (L = iPr₂PCH₂CO₂Me) with NaN(SiMe₃)₂, H₂O, and HCl leads, in the coordination sphere of the metal center, to a conversion of iPr₂PCH₂CO₂Me to iPr₂PCH₂CO₂H via the isolated phosphinyl enolate and phosphinyl acetate complexes as intermediates. In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Product Details of 39722-81-1).

Catalytic C-H Activation of Hydrocarbons by Rhodium(I) and Iridium(I) Complexes with Hemilabile Quinolyl-Cp Ligands was written by Kohl, Gerald;Rudolph, Ralph;Pritzkow, Hans;Enders, Markus. And the article was included in Organometallics in 2005.Related Products of 39722-81-1 This article mentions the following:

The rhodium(I) and iridium(I) complexes I (M = Rh, R = H 3a; M = Ir, R = H 4a; M = Rh, R = Me 5a; M = Ir, R = Me 6a) contain the hemilabile Cp-quinoline chelate ligands, where the hard nitrogen donor does not displace the good acceptor ligand ethylene. After irradiation with visible light, intensely colored complexes are obtained, where the N-donor coordinates to the metal centers. Depending on the metal atom and on the substitution pattern at the Cp rings, the mono-ethene complex with N-metal coordination can be observed spectroscopically (e.g., 3b) or C-H addition products are probable intermediates. The iridium complex 6a is able to activate the aliphatic C-H bond in cyclohexane. With the rhodium complex 5a as the precatalyst, catalytic H/D exchange reactions have been performed with olefinic substrates. With linear α-olefins a fast double-bond isomerization dominates. The hemilabile ligands stabilize the catalytically active metal complexes without suppressing their activity significantly. In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Related Products of 39722-81-1).

Cyclometalation of 6-Phenyl-2,2′-Bipyridine and Iridium: Synthesis, Characterization, and Reactivity Studies was written by Young, Kenneth J. H.;Yousufuddin, Muhammed;Ess, Daniel H.;Periana, Roy A.. And the article was included in Organometallics in 2009.COA of Formula: C8H16Cl2Ir2 This article mentions the following:

Heating the potential tridentate 6-(4-R-phenyl)-2,2′-bipyridine ligand 1a (R = H), and derivatives 1b (R = CMe₃) and 1c (R = OH), with IrCl₃ hydrate in 2-methoxyethanol or acetone/H₂O followed by treatment with pyridine gave the unexpected bidentate cyclometalated NC dinuclear complexes [Ir(NC)Cl₂(C₅H₅N)]₂ (R = H (2aPy), CMe₃ (2bPy), OH (2cPy)), where cyclometalation occurs at the 3-position of the central pyridine ring as the major product. Altering the ligand/metal ratio from 1:1 to 2:1 produced a mixture of bis-cyclometalated complexes, Ir(NNC)(NC)Cl (R = H (3a), CMe₃ (3b), NNC = 6-(2-κ-4-R-C₆H₃)-2,2′-bipyridine-κ²N,N’), with tridentate and bidentate binding modes. Using discrete Ir^I synthons, such as Ir(DMSO)₃Cl or [Ir(cyclooctene)₂Cl]₂, gave a complicated mixture of products. However, when [Ir(C₂H₄)₂Cl]₂ was used, then the desired tridentate cyclometalated Ir(NNC) complex Ir(NNC)Et(C₂H₄)Cl (4) was synthesized cleanly. The dinuclear complex 2a-Py was converted to the corresponding mononuclear dichloride complexes Ir(NC)(NN^tBu)Cl₂ (5a, NN^tBu = κ²N,N’-4,4′-di-tert-butylbipyridine) upon refluxing with 4,4′-di-tert-butylbipyridine in N,N-dimethylacetamide (DMA). Treatment of 5a with ZnMe₂ gives Ir(NC)(NN^tBu)MeCl (6a). Abstraction of the chloride with AgOTf yields Ir(NC)(NN^tBu)MeOTf (7a).
