[PtPh2(dppe)] (dppe = 1,2-bis(diphenylphosphino)ethane) reacts with equimolar [PtCl2(cod)] (cod = 1,5-cyclooctadiene) to give a mixture of [PtPh2(cod)] (38%), [PtCl(Ph)(cod)] (53%) and [PtCl2(dppe)] (72%) via exchange of the Ph and chloro ligands among the Pt complexes. The reaction is strongly inhibited by addition of Cl-. The intermol. Ph ligand transfer from Pd to Pt is observed in the reaction of [PdCl(Ph)(bpy)] (bpy = 2,2′-bipyridine) with [PtX2(cod)] (X = Cl, I), which produces [PtX(Ph)(cod)]. The reaction of [PdCl(Ph)(bpy)] with [PdCl2(cod)], giving [Pd2(μ-Cl)2{(4,5-η-κC1)-(C8H12Ph)}2], occurs much faster than a similar reaction of [PdCl(Ph)(bpy)] with [PtCl2(cod)]. [PtPh2(L2)] (L2 = cod, dppe) reacts with [PdCl2(cod)] in CH2Cl2 at room temperature to afford [Pd2(μ-Cl)2{(4,5-η-κC1)-(C8H12Ph)}2] via intermol. Ph ligand transfer from Pt to Pd and subsequent insertion of a C:C bond of cod into the Pd-Ph bond. Cationic Pd complexes [Pd(acetone)2(cod)]2+(BF4-)2 and [Pd(η3-C3H5)(acetone)2]+ (BF4-) react with [PtPh2(cod)] to form biphenyl. All these results indicate that chloro complexes of Pd and Pt with cod ligand undergo the ligand exchange with the Ph complexes of these metals.

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 Chemical Properties of Mononuclear and Dinuclear Phenylplatinum(II) Hydroxo Complexes with Cod Ligands. Transmetalation of Arylboronic Acids, Coupling of the Phenyl Ligands, and Carbonylation, published in 2006-06-19, which mentions a compound: 12266-72-7, mainly applied to platinum hydroxo complex mononuclear dinuclear phenyl ligand coupling carbonylation; transmetalation arylboronic acid platinum hydroxo cyclooctadiene complex; phenyl group transfer arylboronic acid platinum hydroxo cyclooctadiene complex; crystal structure platinum cyclooctadiene complex preparation; mol structure platinum cyclooctadiene complex, Recommanded Product: Diiodo(1,5-cyclooctadiene)platinum(II).

The reaction of bpy with [{Pt(Ph)(cod)}2(μ-OH)](BF4) (1-BF4; cod = 1,5-cyclooctadiene) in acetone splits a Pt-O bond to yield a mixture of Pt(CH2COMe)(Ph)(cod) (2) and [Pt(Ph)(bpy)(cod)](BF4) (3-BF4), whereas a similar reaction in toluene produces 3-BF4 and Pt(OH)(Ph)(cod) (4). The complex 4 was obtained in solution and was not isolated as anal. pure crystals because of its gradual disproportionation, giving PtPh2(cod) (5). The dinuclear complex 1-BF4 reacts with ArB(OH)2 (Ar = Ph, C6H2F3-2,4,6) to form 5 and Pt(C6H2F3-2,4,6)(Ph)(cod) (6), resp., via aryl group transfer from B to Pt. The accompanying formation of B(OH)3 was confirmed by 11B{1H} NMR spectroscopy. The reaction of BF3·Et2O with 1-BF4 followed by the addition of NH4Cl(aq) produces biphenyl and PtCl2(cod), which takes place possibly via a dinuclear intermediate. The cationic dinuclear complex 1-BF4 reacts with CO (1 atm) to form benzophenone. Since the reactions of AgBF4 with Pt(COPh)(I)(cod) (7) and CO with [Pt(Ph)(THF)(cod)](BF4) also yield benzophenone, the above carbonylation of 1-BF4 is considered to involve mononuclear intermediates. Mechanisms are proposed for some of these reactions.

Synthetic Route of C8H12I2Pt. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Antiproliferative effect of novel platinum(II) and palladium(II) complexes on hepatic tumor stem cells in vitro. Author is Miklasova, Natalia; Fischer-Fodor, Eva; Loennecke, Peter; Tomuleasa, Ciprian Ionut; Virag, Piroska; Perde Schrepler, Maria; Miklas, Roman; Silaghi Dumitrescu, Luminita; Hey-Hawkins, Evamarie.

Novel platinum and palladium complexes with (2-isopropoxyphenyl)dicyclohexylarsine and (2-methoxyphenyl)dicyclohexylarsine ligands were synthesized and tested on different tumor cells. Adducts with general formula MX2L2 (M = Pt(II), Pd(II); X = Cl or I; L = organoarsenic ligand) were fully characterized. According to the crystallog. data, in all complexes the organoarsenic ligands coordinate the metal center through the arsenic atom only, in a trans arrangement with the halogen atoms. The antiproliferative potential of complexes 1-4 was evaluated in vitro on human tumor cell lines. A markedly biol. activity was observed against the chemoresistant hepatic tumor stem cell line, the normal hepatic stem cells and towards the hepatocellular carcinoma (non-stem) cells. The new compounds toxicity is selectively limited in normal liver cells, unlikeness with the oxaliplatin, which displays a more intense effect in normal cells, compared with the two tumor cell lines. The stem cells treatment with compounds 1-4 causes DNA damages; the antimitotic effect of these compounds is based on their genotoxicity and on the capacity to form crosslinks with the DNA interstrand. In the case of platinum complexes 1 and 3 this mechanism gives rise to specific lesions on DNA that induces apoptosis in stem cells, influencing their selectivity in tumor cell growth inhibition. Compounds 1, 2 and 4 display higher activity against tumor stem cells. The novel platinum complexes 1 and 3 are more efficient against tumor stem cells than oxaliplatin, and if used in combination with sorafenib-based monoclonal anticancer therapy, complexes 1, 3 and 4 have the ability to induce superior chemosensitivity relative to sorafenib than the standard platinum-based drug, making them promising candidates for prodrug development.

A series of three platinum(II) halide complexes 2-4 [Pt(X)2{Nap(PPh2)(SPh)}] (Nap = naphthalene-1,8-diyl; X = Cl, Br, I) and a ruthenium(II) p-cymene complex 5 [Ru(η6-MeC6H4iPr)(Cl){Nap(PPh2)(SPh)}]+Cl- of the sterically crowded peri-substituted naphthalene phosphine 1 have been prepared The compounds were fully characterised by multinuclear NMR, IR and MS and x-ray data for 1-5 are compared. Mol. structures are analyzed by naphthalene ring torsions, peri-atom displacement, splay angle magnitude, P···S interactions, aromatic ring orientations and geometry around the metal center. Platinum adopts a strictly square planar geometry which increases the distortion of the naphthalene skeleton in 2-4. Conversely, the classical-piano stool conformation of 5 results in a pseudo-octahedral conformation around the ruthenium atom which influences the naphthalene geometry to a much lesser extent with distortion of a similar magnitude to the free ligand 1.

The new chiral ligands 2-butyl-8-chloro-1-(4,8-di-tert-butyl-2,10-dimethoxy-5,7-dioxa-6-phosphadibenzo[a,c]cycloheptin-6-yl)-1,2-dihydroquinoline (biphenphoshquin, I) and 2-butyl-8-chloro-1-(3,5-dioxa-4-phosphacyclohepta[2,1-a;3,4-a’]-dinaphthalen-4-yl)-1,2-dihydroquinoline (binaphoshquin, II, SaRC, SaSC) were synthesized starting from the rigid backbone of 8-chloroquinoline. The reactions of I and II with Rh(I), Pd(II), and Pt(II) substrates are reported. The reaction of I with [Rh(CO)2Cl]2 in a 2:1 molar ratio in hexane afforded a binuclear chloro-bridged Rh(III) species by intramol. oxidative addition of the C-Cl bond of ligand I across the Rh(I) centers. The Rh(III) complex (III), incorporating the enantiomers SaRC-I and RaSC-I, [Rh(μ-Cl)(CO)Cl(I)]2, was fully characterized by x-ray diffractometry. Reactions of [Pd(PhCN)2Cl2] with the ligands I and SaRC-II in 1:2 molar ratio in toluene afforded the products cis-[PdI2Cl2] and cis-[Pd(SaRC-II)2Cl2].

Keywords: CellScan laser spectroscopy platinum complex organoarsenic ligand antitumor.They researched the compound: Diiodo(1,5-cyclooctadiene)platinum(II)( cas:12266-72-7 ).Formula: C8H12I2Pt. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:12266-72-7) here.

The present paper examines one of the multiple uses of the CellScan technique, its utilization in the biol. evaluation of novel compounds, in order to improve the methods concerning the prediction of their anti-proliferative effects and application as anti-cancer drugs. The CellScan is a laser scanning static cytometer, enabling repetitive spectroscopic measurements in intact living cells. The detection of cell viability and apoptosis is possible, based on the transformations that occur in the cytoplasm matrix of tumor cells influenced by cytotoxic compounds The measurement of fluorescence changes, due to this phenomenon, is possible with the CellScan system. The potential of this technol. to detect the in vitro effects of the inhibitory mols. on tumor cells was demonstrated, making this method a valuable tool for chemosensitivity tests. We synthesized and fully characterized three novel platinum complexes of tertiary arsine ligands: trans-[PtI2(2-iPrOC6H4AsPh2)2] (1), trans-[PtCl2(2-MeOC6H4AsPh2)2] (2) and cis-[PtCl2(2-HOC6H4AsPh2)2] (3). The three compounds are biol. active against tumor cells and their cytotoxicity is comparable with standard drugs. Measurements using the CellScan technol. correlate well with the results provided by other bioassay methods.
