Recommanded Product: 12266-72-7. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Trimetallic complexes of the tripod ligand 1,1,1-tris(diphenylphosphinomethyl)ethane. Part I. Homotrimetallic cis,cis,cis and cis,trans,cis complexes of the type [(PtX2-η-tripod)2PtX2] (X = Cl, I and CH3). Author is Khan, A. Rauf; Socol, Steven M.; Meek, Devon W..

Cis,cis,cis- and cis,trans,cis-[(PtX2-η-tripod)2PtX2] (X = Cl, I and Me; tripod = 1,1,1-tris(diphenylphosphinomethyl)ethane) were isolated and were shown by both 31P and 195Pt NMR spectroscopy to possess phosphino-bridged trimetallic structures. The assignment of these structures is established from 1J(Pt-P) couplings and the coordination chem. shift, ΔP, of the dangling phosphino group of the monometallic complexes upon coordination. In both cis,cis,cis and cis,trans,cis geometries, the 31P NMR chem. shift of the chelating P atoms and the 195Pt NMR chem. shift for the [PtX2(tripod)] complexes remain unperturbed upon coordination of the previously noncoordinated P. For the monomeric complexes of tripod, trends in the 31P and 195Pt NMR chem. shifts as a function of X parallel those which were previously reported for analogous complexes which contain monodentate ligands.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis and solid-state characterization of platinum complexes with hexadentate amino- and iminophosphine ligands, published in 2009-10-07, which mentions a compound: 12266-72-7, mainly applied to phosphinophenylaminocyclohexane preparation coordination platinum; hexadentate amino imino phosphine ligand preparation coordination platinum; crystal mol structure phosphinophenylaminocyclohexane phosphinophenyliminocyclohexane platinum complex, Application In Synthesis of Diiodo(1,5-cyclooctadiene)platinum(II).

Hexadentate ligands cis,cis-C6H9(N:CHC6H4(PPh2))3 (1) and cis,cis-C6H9(NHCH2C6H4(PPh2))3 (2) were synthesized starting from cis,cis-1,3,5-triaminocyclohexane, and characterized using NMR spectroscopy and single-crystal x-ray diffraction. These ligands can bind both Pt(0) and Pt(II) metal centers using either or both of the soft phosphine moieties and the hard amine/imine moieties. In many cases the resulting complexes are negligibly soluble; hence, 31P and 195Pt solid-state NMR (SSNMR) spectroscopy was applied to analyze the bonding modes of the hexadentate ligands. The 195Pt SSNMR spectroscopy of these complexes is particularly challenging, since 1H-195Pt cross polarization is extremely inefficient, the 195Pt longitudinal relaxation times are extremely long and the 195Pt powder patterns are expected to be quite broad due to platinum chem. shift anisotropy. It is demonstrated that the ultra-wideline 195Pt SSNMR spectra can be efficiently acquired with a combination of frequency-stepped piecewise acquisitions and cross-polarization/Carr-Purcell Meiboom-Gill (CP/CPMG) NMR experiments The 195Pt and 31P SSNMR data are correlated to important structural features in both Pt(0) and Pt(II) species.

The trimethylsilanethiolate complexes of the platinum triad metals (dppe)M(SSiMe3)2 (M = Ni, Pd, Pt) and (COD)Pt(SSiMe3)2 were prepared by the reaction of NaSSiMe3 with (dppe)MCl2 or (COD)PtI2. These complexes are water-sensitive. New, sulfido-bridged heterobimetallic complexes L2M(μ3-S)2{Ru(N)Me2}2 resulted from the reactions of (dppe)Pt(SSiMe3)2, (COD)Pt(SSiMe3)2, or (dppe)Pd(SSiMe3)2 with [PPh4][Ru(N)Me2Cl2]. The reaction between (dppe)Pt(SSiMe3)2 and [Os(N)(CH2SiMe3)2(NCMe)2][BF4] produced (dppe)Pt(μ3-S)2{Os(N)(CH2SiMe3)2}2.

Compound: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Reactions of an azine diphosphine with platinum(II) and palladium(II) and the formation of a novel heterocyclic diphosphine ligand. Crystal structure of [PdI2{PPh2CH=C(But)N-N=C(But)CH2PPh}].COA of Formula: C8H12I2Pt.

The azine diphosphine Z,Z-PPh2CH2C(CMe3)=N-N=C(CMe3)CH2PPh2 (1) was treated with [PtMe2(cod)] (cod = cycloocta-1,5-diene) to give the dimethylplatinum(II) complex [PtMe2{PPh2CH2C(CMe3)=N-N=C(CMe3)CH2PPh2}] (1a) containing a 9-membered chelate ring with an E,Z configuration for the bidentate azine diphosphine ligand. This complex undergoes oxidative addition with MeI to give the fac-trimethylplatinum(IV) complex [PtMe3I{PPh2CH2C(CMe3)=N-N=C(CMe3)CH2PPh2}] (2). The corresponding Pt(II) complexes [PtX2{PPh2CH2C(CMe3)=N-N=C(CMe3)CH2PPh2}] (X = CCC6H4Me-p (1b) or Cl (1c)) were also prepared Treatment of trans-[PtCl2(NCR)2] (R = Me or Ph) with 1 gave hexanuclear trans-[{PtCl2[PPh2CH2C(CMe3)=N-N=C(CMe3)CH2PPh2]}6] (3a) in which the azine diphosphine is acting as a bridging group and is still sym., i.e. the configuration is still Z,Z. The Pd analog (3b) was made by treating [PdCl2(NCPh)2] or Na2[PdCl4] with 1 but might only be binuclear. This complex was unstable in hot CHCl3 and at 60° (30 min) was completely converted into [PdCl{PPh2CH2C(CMe3)=N-N=C(CMe3)CH2PPh2}]Cl (4a) in which the azine diphosphine is tridentate with E,Z configuration and mutually trans-coordinated P donors and 1 of the azine nitrogens is coordinated. Treatment of [PtCl2(cod)] with 1 and addition of NH4PF6 gave the Pt salt [PtCl{PPh2CH2C(CMe3)=N-N=C(CMe3)CH2PPh2}]PF6 (4c); [PtI{PPh2CH2C(CMe3)=N-N=C(CMe3)CH2PPh2}]I (4d) was also prepared On prolonged (8 d) heating in CHCl3 solution the bridged complex 3b was quant. converted into the novel and very stable heterocyclic complex [PdCl2{PPh2CH=C(CMe3)N-N=C(CMe3)CH2PPh}] (5a) with loss of a mol. of benzene. Treatment of 5a with LiBr or NaI gave the corresponding dibromide (5b) or diiodide (5c) complexes. The crystal structure of 5c was determined The corresponding Pt complexes [PtX2{PPh2CH=C(CMe3)N-N=C(CMe3)CH2PPh}] (5d-5f) (X = Cl, Br or I) were also prepared and treatment of the dichloro complex with MgMeI gave the di-Me complex (5g). Treatment of this di-Me complex with an excess of MeI gave [PtMe3I{PPh2CH=C(CMe3)N-N=C(CMe3)CH2PPh}] (6). Proton, 13C{1H} and 31P{1H} NMR and IR data are given.

COA of Formula: C8H12I2Pt. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Electronic Interactions in Iron- and Ruthenium-Containing Heterobimetallic Complexes: Structural and Spectroscopic Investigations. Author is Serra, Daniel; Abboud, Khalil A.; Hilliard, Casie R.; McElwee-White, Lisa.

The heterobimetallic half-sandwich ruthenium complexes and their isoelectronic iron analogs, bridged by iodide and dppm ligands with Pt(II), Pd(II) and Au(I) moieties exhibit greater degree of interaction between the two metallic centers bridged by both iodide and dppm (for Pt, Pd) than for those bridged only by dppm (for Au complexes). Complexation of [CpM(CO)(I)(κ1-dppm)] (6, 7; M = Ru, Fe) with (COD)M1I2 (M1 = Pt, Pd) or AuI gave bimetallic complexes [Cp(CO)M(μ-I)(μ-dppm)M1I2] (8 M = Ru, M1 = Pt; 9 M = Fe, M1 = Pt; 10 M = Ru, M1 = Pd; 11 M = Fe, M1 = Pd) and [Cp(CO)M(I)(μ-dppm)AuI] (12 M = Ru; 13 M = Fe); similar reaction of [CpRu(PPh3)(I)(κ1-dppm)] (17) with [Pd(COD)Cl2] gave the triphenylphosphine analog [Cp(PPh3)Ru(μ-I)(μ-dppm)PdI2] (15). Crystal structure determination for 8-11 shows square-planar geometry around M1(II) center with phosphorus ligand trans- to the terminal iodide. Complexes 8-13 were characterized by cyclic voltammetry, IR, UV, and NMR (1H and 31P) spectroscopy, and elemental anal. Electronic interaction between the two metals is significant for the iodide-bridged compounds 8-11, as evidenced by the variation in their carbonyl stretching frequencies and UV-vis spectra, as well as in the shifts of their redox potentials in comparison to the shifts for mononuclear model compounds In contrast, gold compounds 12 and 13, which have only dppm bridges, exhibit limited interactions between the two metals.

Author is Lappert, Michael F.; Martin, Tony R.; Raston, Colin L.; Skelton, Brian W.; White, Allan H..

A high-yield synthesis of a THF solution of the di-Grignard reagent [I; o-(ClMgCH2)2C6H4] from o-(ClCH2)2C6H4 is described, as well as that of an analog obtained from 1,2-(ClCH2)2C6H2Me2-4,5. Cooling I to ∼-40° gives colorless Mg(CH2C6H4CH2-o)L (L = THF) of unknown structure, whereas at ambient temperature a concentrated solution (≳0.1 mol/dm3) slowly deposits colorless needles of [Mg(CH2C6H4CH2-o)L2]3 (II). The crystal and mol. structure of II was determined by x-ray diffraction and refined by least squares to R 0.054 for 1117 observed reflections. The mol. is a trimer, the trimeric unit lying on a crystallog. 2-fold axis. Each of the 3 Mg atoms is bridged to the other 2 by a CH2C6H4CH2 ligand, and the pseudotetrahedral coordination about each Mg is completed by a pair of THF mols. The utility of I as a metallocycle precursor is shown by synthesis of the cyclic complex (COD)Pt(CH2C6H4CH2-o) (COD = 1,5-cyclooctadiene) from (COD)PtI2. In contrast, the Li reagent [C6H4(CHSiMe3)2-o][LiL1]2 [L1 = Me2N(CH2)2NMe2] reacts with (dppe)PtCl2 [dppe = Ph2P(CH2)2PPh2] to give (dppe)2Pt.
