Author is Clark, H. C.; Manzer, L. E..

An improved synthesis for PtR2(COD) (COD = 1,5-cyclooctadiene; R = I, Me, Et, PhCH2, Me3SiCH2, Ph) and the reactions with HCl to give PtRCl(COD) are described. The coupling constant J(Pt-H) to the olefinic carbons varies with the trans-influence of the trans-ligand. Displacement of COD from PtMe2(COD) by L (L = isocyanide, phosphine, amine, bipyridyl (bipy), Me3As) gave cis-PtMe2L2. The oxidative addition of MeI to PtR2(COD)(R = Me, Et) gave the Pt(IV) compounds [PtMe3I]4 and [PtMeEt2I]4. MeEt2PtI reacted with 4-methylpyridine (γ-Pic) to give PtEt2Me(γ-Pic)2I and with AgClO4 and pyridine to give [Pt(Et)2Mepy3](ClO4). The reaction of R2Pt(COD) (R = Me, Et) with iodine or bromine gave [PtR2X2]x. In PtMe2(CNEt)2Br2 coupling of the 14N nucleus with the Et H is observed The reaction of AcCl with PtMe2(COD) gave [PtMe2(COMe)Cl]4. γ-Picoline with the acyl compound gave 2 isomers of PtMe2(COMe)(γ-Pic)2Cl as predicted by cleavage of a cubane-type structure. The reaction of iodine with PtR2(COD)(R = CH2Ph) gave a mixture of [PtR2I2]x and PtRI(COD), whereas for R = Me3SiCH2 only PtRI(COD) was obtained. F3CI reacted with PtMe2(COD) to give Pt(CF3)2(COD) and displacement reactions of COD with ligands L, [L = CNC2H5, PhPMe2, Me3As, bipy, γ-Pic, Ph3Sb, Ph3As, Ph2PCCPPh2, Me2NCH2CH2NMe2) gave cis-Pt(CF3)2L2. Oxidative addition reactions with iodine and the stereochem. of the resultant PtIV compounds are described.

SDS of cas: 12266-72-7. 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 Heteropolytopic phosphanylarylthiolato ligands: formation of cis isomers of nickel(II), palladium(II) and platinum(II) complexes with 1-P(Biph)-2-SHC6H4 (Biph = 1,1′-biphenyl-2,2′-diyl). Author is Hildebrand, Alexandra; Sarosi, Imola; Loennecke, Peter; Silaghi-Dumitrescu, Luminita; Sarosi, Menyhart B.; Silaghi-Dumitrescu, Ioan; Hey-Hawkins, Evamarie.

Reaction of the ditopic phosphanylarylthiol 1-P(Biph)-2-SHC6H4 (BiphPSH, Biph = 1,1′-biphenyl-2,2′-diyl), prepared by lithiation-electrophilic substitution, with NiCl2·6H2O, Na2[PdCl4] and [PtI2(cod)] (cod = 1,5-cyclooctadiene) in a 2:1 ratio and in the presence of NEt3 gave exclusively cis isomers of the square-planar complexes cis-[M{(1-P(Biph)-2-S-C6H4)-κ2S,P}2] ([M{(BiphPS)-κ2S,P}2]; M = Ni (1), Pd (2), Pt (3)). D. functional calculations support the assumption that this is probably due to intramol. π-π interaction of the biphenyl groups, which results in enhanced stability of the cis isomers. Compound 1 is the first example of a structurally characterized mononuclear cis-bis(phosphanylthiolato)nickel(II) complex. Small amounts of trinuclear [{PtI(1-P(Biph)-μ-2-S-C6H4-κ2S,P)}3] (4) are also formed besides the mononuclear Pt bis-chelate complex 3.

Product Details of 12266-72-7. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Platinum(II) complexes of the tridentate thioether ligands RS(CH2)3S(CH2)3SR (R = Et, iPr, Ph). Structures of [PtCl(iPrS(CH2)3S(CH2)3SiPr)][BF4], [PtI(PhS(CH2)3S(CH2)3SPh)][BF4], and [Pt(PPh3)(iPrS(CH2)3S(CH2)3SiPr)][BF4]2·CH2Cl2.

The tridentate thioether ligands RS(CH2)3S(CH2)3SR (L1, R = Et; L2, R = iPr, L3, R = Ph) were synthesized by nucleophilic addition of thiolate, SR-, to the ditosylate TsO(CH2)3S(CH2)3OTs. [PtX(Ln)][BF4] were prepared by displacement of 1,5-COD from [PtX2(1,5-COD)] (X = Cl, I) in the presence of one equivalent of AgBF4 and one equivalent of thioether ligand. [PtCl(L2)][BF4] crystallized in the monoclinic space group P21/c with a 10.409(6), b 14.180(4), c 13.726(8) Å, β 104.49(4)°, and Z = 4. The structure refined to R = 5.62% and Rw = 6.86% for 2121 reflections with F°2 > 3σ(F°2). [PtI(L3)][BF4] crystallized in the monoclinic space group P21/n with a 13.415(4), b 12.350(5), c 14.316(5) Å, β 107.48(3)°, and Z = 4. The structure refined to R = 4.85% and Rw = 6.33% for 2168 reflections with F°2 > 3σ(F°2). In both compounds, the thioether ligand acts as a tridentate chelator occupying three of the four sites of the square-planar Pt(II) complex. Variable temperature 13C{1H} NMR verified that there are three possible stereoisomers for these complexes resulting from inversion at S: meso-A, meso-B, and racemic. Thermodn. parameters were calculated for the interconversion among isomers of [PtCl(L2)][BF4] by a full line-shape anal. Removal of the chloride ligand from [PtCl(L2)][BF4] with Ag+ in the presence of PPh3 yielded the phosphine adduct [Pt(PPh3)(L2)][BF4]2, which crystallized in the triclinic space group P1̅ with a 13.266(3), b 11.315(2), c 13.970(2) Å, α 106.04(2), β 84.95(2), γ 86.56(2)°, and Z = 2. The structure refined to R = 4.22% and Rw = 5.38% for 4493 reflections with F°2 > 3σ(F°2). Unlike the two halide complex structures, which crystallized in the meso-B form, [Pt(PPh3)(L2)][BF4]2 crystallized in the racemic form.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Diiodo(1,5-cyclooctadiene)platinum(II)(SMILESS: I[Pt]I.C1=CCC/C=CCC/1,cas:12266-72-7) is researched.Formula: C12H12N2. The article 《Molecular recognition – allosterism generated by weak host-guest interactions in molecular rectangles》 in relation to this compound, is published in European Journal of Inorganic Chemistry. Let’s take a look at the latest research on this compound (cas:12266-72-7).

Two metal-based mol. rectangles (for example, I) that bear two identical binding sites form host-guest adducts with analogous planar Pt2+ complexes (for example, II and III). The larger of the guests III shows no binding allosterism with either of the two rectangles but substantial pos. allosterism is observed when the smaller guest II binds to the rectangles. It is proposed that the smaller guest is better accommodated in the binding sites of the receptor and that this leads to allosterism. Various experiments including 1H NOESY spectroscopy support the supposition that the smaller guest is better incarcerated in the receptors. The mol. structure of the 1:2 host-guest adduct of I:III was determined by X-ray crystallog.

Compound: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Facile intramolecular silicon-carbon bond activation at Pt0 and PtII centers, the main research direction is platinum silyl diphosphine complex preparation oxidative addition reductive elimination; crystal structure platinum pincer silyl diphosphine complex; mol structure platinum pincer silyl diphosphine complex.COA of Formula: C8H12I2Pt.

The compound (2-Cy2PC6H4)2SiMe2 (1) reacted readily with Pt(PPh3)4 to undergo Si-C(sp3) bond cleavage and form the PtII species (Cy-PSiP)PtMe [2, Cy-PSiP = (2-Cy2PC6H4-κP)2SiMe–κSi]. The silane 1 also undergoes Si-C(sp3) bond activation with the PtII precursor [(Me2S)PtMe2]2 to generate 2. Two intermediate species were observed in situ during the reaction of 1 with [(Me2S)PtMe2]2. One intermediate was tentatively assigned as the bis(phosphino) PtII species (κ2-Cy-PSiP)PtMe2 (4), which was crystallog. characterized. A second intermediate (5) was tentatively assigned as the PtIV species (Cy-PSiP)PtMe3 resulting from Si-C(sp3) bond cleavage in 4. In an effort to prepare a (Cy-PSiP)PtIV species that may serve as a model for 5, complex 2 was reacted with MeI and I2, resp.; both reactions resulted in the quant. formation of the Pt(II) complex [(Cy-PSiP)PtI] (6), which could also be independently prepared by the reaction of (COD)PtI2 with (Cy-PSiP)H. The reaction of (Cy-PSiP)H with PtMe3I resulted in the formation of a PtIV species (7) as the major product. Complex 7 was tentatively assigned as (Cy-PSiP)PtMe2I, and undergoes relatively facile reductive elimination of ethane to form 6.

L (I) reacted with (COD)PtI2 (COD = 1,5-cyclooctadiene) in toluene to give cis-PtL2I2 in which L coordinates through the Sb atom. L reacted with trans-[MePt(PPh3)2(Me2CO)]SbF6 in ether to give trans-MePt(PPh3)2L. trans-MePt(PPh3)2L.0.5(Me3Si)2O is monoclinic, space group P21/c, with a 1246.6(3), b 1752.9(4), c 2749.3(5) pm, β 92.64(2)°, Z = 4, d.(calculated) = 1.49 g cm3, R = 0.065, Rw = 0.090 for 4337 reflections. Changes in the bond angles and lengths in L upon coordination are attributed to steric congestion at the Pt atom due to 2 trans PPh3 ligands. In spite of steric congestion the L system maintains its 10-electron count and planar ligand backbone. NMR data for both complexes require the presence of a stereoactive bond pair at the Sb center.

Author is Shiotsuka, Michito; Tanamachi, Takahiro; Urakawa, Tsuyoshi; Matsuda, Yoshihisa.

The novel platinum and palladium complexes with phosphorin, [Pt(dmppn)2X2] (X = Cl, 1; Br, 2; I, 3) and [Pd(dmppn)2X2] (X = Cl, 4; Br, 5), were prepared using 4,5-dimethyl-2-phenylphosphorin (dmppn) with M(cod)X2 or M(PhCN)2X2 (M = Pt, Pd). The crystal structure of 3 was determined by single crystal x-ray crystallog. and shown a cis configuration in a square planar structure. The chem. shifts for these complexes were observed by 31P{1H} NMR spectroscopy in the solution and they showed significant upfield shifts over 30 ppm relative to that of the free ligand. These upfield shifts indicate that the phosphorin ligand undergoes strong π-back donation from the central metal compared with general phosphine ligands and the difference of these upfield shifts between Pt and Pd is clearly appeared the degree of π-back donation from the central metal. The platinum and palladium complexes in solution also exhibit cis square planar configurations as shown by 31P{1H} and 13C{1H} NMR data.
