Asymmetric Cycloisomerization of o-Alkenyl-N-Methylanilines to Indolines by Iridium-Catalyzed C(sp³)-H Addition to Carbon-Carbon Double Bonds was written by Torigoe, Takeru;Ohmura, Toshimichi;Suginome, Michinori. And the article was included in Angewandte Chemie, International Edition in 2017.Electric Literature of C8H16Cl2Ir2 This article mentions the following:

Highly enantioselective cycloisomerization of N-methylanilines, bearing o-alkenyl groups, into indolines, e.g., I, is established. An iridium catalyst bearing a bidentate chiral diphosphine effectively promotes the intramol. addition of the C(sp³)-H bond across a carbon-carbon double bond in a highly enantioselective fashion. The reaction gives indolines bearing a quaternary stereogenic carbon center at the 3-position. The reaction mechanism involves rate-determining oxidative addition of the N-Me C-H bond, followed by intramol. carboiridation and subsequent reductive elimination. In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Electric Literature of C8H16Cl2Ir2).

Rhodium and Iridium Complexes Bearing “Capping Arene” Ligands: Synthesis and Characterization was written by Gu, Shunyan;Musgrave, Charles B.;Gehman, Zoe M.;Zhang, Ke;Dickie, Diane A.;Goddard, William A.;Gunnoe, T. Brent. And the article was included in Organometallics in 2021.Safety of Chlorobis(ethylene)iridium(I) dimer This article mentions the following:

A series of olefin-coordinated Rh^I and Ir^I complexes bearing “capping arene” ligands (5–^XFP and 6–^XFP) of the general formulas (FP)M(olefin)X, [(FP)M(olefin)₂][M(olefin)₂X₂], and [(FP)M(olefin)₂]BF₄ (FP = “capping arene” ligands, X = halide or pseudohalide, olefin = ethylene, cyclooctene, (olefin)₂ = (C₂H₄)₂ or cyclooctadiene) were synthesized and characterized. Single-crystal X-ray diffraction studies revealed structural differences that are a function of the identity of the capping arene ligand and the metal. For 5–^XFP ligands (5–^XFP = 1,2-bis(N-7-azaindolyl)-benzene and derivatives with substituents on the arene moiety), the coordination to both Rh and Ir gives rise to complexes that are best described as 16-electron and square planar. For 6–^XFP ligands (6–^XFP = 8,8′-(1,2-phenylene)diquinoline and derivatives with substituents on the arene moiety), the structures of Rh and Ir complexes are better considered as 18-electron and trigonal bipyramidal due to an 畏²-C,C interaction between the metal center and the arene group of the capping arene ligand. Variable-temperature ¹H NMR spectroscopy studies of ethylene rotation demonstrated that the Ir complexes possess higher activation barriers to rotation in comparison to Rh complexes and the 6–^XFP complexes tend to give ethylene higher rotational barriers in comparison to 5–^XFP complexes for complexes of the type (FP)Rh(畏²-C₂H₄)Cl. DFT calculations are consistent with enhanced Rh to ethylene 蟺-back-donation for Rh complexes ligated by the 6–^XFP ligands in comparison to the 5–^XFP ligands. In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Safety of Chlorobis(ethylene)iridium(I) dimer).

Preparation and spectroscopic study of functionally substituted cyclopentadienides of thallium(I), potassium, rhodium(I), and iridium(I) was written by Arthurs, Michael;Al-Daffaee, Hafid K.;Haslop, John;Kubal, Gina;Pearson, Matthew D.;Thatcher, Peter;Curzon, Eirian. And the article was included in Journal of the Chemical Society, Dalton Transactions: Inorganic Chemistry (1972-1999) in 1987.Category: chlorides-buliding-blocks This article mentions the following:

The different patterns observed for the ring nuclei in ¹³C and ¹H NMR study of a series of monosubstituted cyclopentadienide compounds of type M(C₅H₄X) [M = K, Tl; X = Cl, COMe, CO₂Me, CHO, Ph, COCO₂Et, C(CN):C(CN)₂] reflect both the Lewis acid character of the metal and the electronic effect of the substituent. Fluxional behavior is observed for K(C₅H₄COMe). Pseudo-first-order rate constants have been evaluated for H-D exchange in several of the K compounds The Th(I) compounds generally exhibit greater synthetic utility than their K analogs and several have been used in the synthesis of new [M(畏⁵-C₅H₄X)(畏²-C₂H₄)₂] (M = Rh, Ir) complexes. Activation barriers for alkene rotation and mass spectral fragmentation patterns are discussed for these compounds The ¹H NMR spectra for the cyclopentadienyl ring indicate that the M-ring bonding is not fully delocalized. Anal. of the products resulting from reaction between ClCO₂Me and K(C₅H₅) confirm the strongly electrophilic character of the former reagent.

Treatment of [IrCl(C₂H₄)₂]₂ with the phosphino ester iPr₂PCH₂CO₂Me affords the mononuclear complex trans-[IrCl(C₂H₄)(iPr₂PCH₂CO₂Me-魏P)₂], which reacts with CO to give trans-[IrCl(CO)(iPr₂PCH₂CO₂Me-魏P)₂] (I) and with HC顚咰R to give [IrH(C顚咰R)Cl(iPr₂PCH₂CO₂Me-魏P)(iPr₂PCH₂CO₂Me-魏³P,O)] (R = Ph, CO₂Me). Upon heating, these alkynylhydridoiridium compounds rearrange to yield the isomeric vinylidenemetal derivatives trans-[IrCl(:C:CHR)(iPr₂PCH₂CO₂Me-魏P₂)] (II, R = Ph, CO₂Me). Reaction of I or II with Al₂O₃/H₂O leads to cleavage of a CH₃-O bond of one phosphino ester ligand and gives the iridium chelate complexes [Ir(L)(iPr₂PCH₂CO₂Me-魏P)(iPr₂PCH₂CO₂-魏³P,O)] (III, L = CO, C:CHPh, C:CHCO₂Me) in 80-90% yield. III (L = CO) reacts with Me iodide by oxidative addition to form the octahedral complex [IrI(CH₃)(CO)(iPr₂PCH₂CO₂Me-魏P)(iPr₂PCH₂CO₂-魏²P,O)]. The X-ray crystal structure of III (L = CO) has been determined In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Synthetic Route of C8H16Cl2Ir2).

Synthesis, Structure, and Reactivity of Iridium(III) Complexes Containing a 4,6-Dimethyl-1,3-benzenediphenylimine Pincer Ligand was written by Wingard, Leah A.;Finniss, Mathew C.;Norris, Michael;White, Peter S.;Brookhart, Maurice;Templeton, Joseph L.. And the article was included in Inorganic Chemistry in 2013.Recommanded Product: Chlorobis(ethylene)iridium(I) dimer This article mentions the following:

A nonheterocyclic bis(imino)aryl ligand with blocking Me substituents, 4,6-dimethyl-1,3-benzenediphenylimine (NCHN), has been synthesized. Metalation via oxidative addition proceeds under mild conditions with the Ir(I) reagent [Ir(CH₂=CH₂)₂(Cl)]₂ to produce the Ir(III) product (NCN)Ir(CH₂CH₃)(Cl). Neutral nucleophiles such as water or triphenylphosphine add readily to the vacant sixth coordination site. Protonation of the Et group results in loss of ethane and formation of a dicationic chloride-bridged (NCN)Ir dimer. Alternatively, the chloride ligand can be abstracted from (NCN)Ir(CH₂CH₃)(Cl) to provide access to various neutral and cationic species, including (NCN)Ir(CH₂CH₃)(OAc) (OAc = acetate), [(NCN)Ir(CH₂CH₃)(bpy)][BF₄] (bpy = 4,4′-bipyridine), [(NCN)Ir(CH₂CH₃)(NCCH₃)₂][BF₄], and [(NCN)Ir(CH₂CH₃)(OH₂)₂][BF₄], which is water soluble In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Recommanded Product: Chlorobis(ethylene)iridium(I) dimer).

Supported transition-metal catalysts for the C-C coupling reaction between ethene and diazoalkanes was written by Schneider, M. E.;Moehring U.;Werner, H.. And the article was included in Journal of Organometallic Chemistry in 1996.COA of Formula: C8H16Cl2Ir2 This article mentions the following:

The preparation of series of immobilized transition-metal catalyst are reported. The catalysts were obtained by chemisorption either Rh(I) complexes [MX(C₂H₄)₂]_n (M = Rh, Ir; X = Cl, OAc, acac, f₃-acac, f₆-acac) on SiO₂ or MgO supports. The oxides were also activated by SiCl₄ or TiCl₄ to give support materials in which the acidic nature of the surface is substantially increased. The activity of the immobilized catalysts was tested, particularly in the reaction of ethene with diphenyldiazomethane which yields a mixture of 1,1-diphenylpropene (8) and 1,1-diphenylcyclopropane (9). The most active and most selective (highest ratio 8:9) catalyst B1 was formed from support material B (SiO₂ activated by SiCl₄) and [RhCl(C₂H₄)₂]₂ (1) and both the activity and selectivity of B1 was comparable with that of complex 1 in solution In contrast, the supported catalysts A2, D2 and A3, D3 obtained from [Rh(OAc)(C₂H₄)₂]₂ (2) and [Rh(acac)(C₂H₄)₂] (3) and silica (A) and MgO (D) were less active than compounds 2 and 3 in solution The immobilized catalysts A6, A7, D7 and E7, which were generated from the chloro- and acetatoiridium(I) complexes [IrCl(C₂H₄)₂]₂ (6) and [Ir(OAc)(C₂H₄)₂]₂ (7), possessed a lower activity than the Rh counterparts. With diazoalkanes other than Ph₂CN₂, the activity of the supported catalyst B1 was partly higher and partly lower than that of 1 in the homogeneous phase. In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1COA of Formula: C8H16Cl2Ir2).

Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).COA of Formula: C8H16Cl2Ir2
