Book Synopsis Reactivity of Dimethylplatinum(II) Complexes with Peroxides by : Kyle Richard Pellarin
Download or read book Reactivity of Dimethylplatinum(II) Complexes with Peroxides written by Kyle Richard Pellarin and published by . This book was released on 2012 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a study of dimethylplatinum(II) complexes containing bidentate nitrogen donor ligands. This work deals with the oxidative addition of peroxides and focuses on synthesis, characterization and reaction mechanisms of these complexes. Dimethylplatinum(II) complexes were reacted with oxidants dimethyldioxirane (DMDO), meta-chloroperbenzoic acid (m-CPBA) and phthaloyl peroxide. The use of these oxidants has allowed for the synthesis of novel platinum(IV) complexes by oxidative addition and the formation of unique supramolecular networks. The formation of both trans- and cis-oxidative addition products was controlled by the type of oxidant utilized. By varying the ligand design of the platinum(II) complexes, the formation of the multiple platinum(IV) complexes have been obtained, each demonstrating their own unique chemistry. In other interests, low temperature 1H NMR spectroscopy has been utilized to follow the reaction pathway of the oxidative addition of iodine at [PtMe2(bpy)]. This technique allowed for the observation of intermediates formed within this reaction. The formation of intermediates shows solvent dependence following the trend; acetone>CD2Cl2> toluene, suggesting there is stabilization of these intermediates by more polar solvents.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a study of dimethylplatinum(II) and dimethylplatinum(IV) complexes containing bidentate nitrogen donor ligands. This work deals with oxidative addition, and reductive elimination chemistry, and it focuses on synthesis, characterization, and reaction mechanisms in studies of these complexes. The compound [PtMe2(bpe)], bpe = 1,2-bis(2-pyridyl)ethane, is easily oxidized to give octahedral organoplatinum(IV) complexes and the subsequent chemistry is profoundly influenced by the accompanying strain induced in the 7-membered Pt(bpe) chelate ring. On reaction of [PtMe2(bpe)] with HCl, the initial product [PtHClMe2(bpe)] undergoes reductive elimination of methane to form [PtClMe(bpe)]. In contrast, methyl iodide reacts with [PtMe2(bpe)] to give [PtIMe3(bpe)], and this decomposes by loss of the bpe ligand to give the cubane [(PtIMe3)4] and not by reductive elimination. Finally, a new class of platinum(IV) double cubane clusters was obtained on oxidation of complex [PtMe2(bpe)] with either hydrogen peroxide to give [Pt4( -OH)4(3-OH)2Me10], as a mixed complex with [PtMe2(CO3)(bpe)], or with oxygen in methanol to give [Pt4( -OH)2( -OMe)2(3-OMe)2Me10]. The oxidation of the complex [PtMe2(bps)], bps = bis(2-pyridyl)-dimethylsilane, by oxygen, hydrogen peroxide or dibenzoyl peroxide in the presence of water or alcohol gives the complex cation, [PtMe3(k3-N, N, O-HOSiMe(2-C5H4N)2)]+, in a reaction involving easy cleavage of a methylsilicon bond. Treatment of the complex [PtMe2(bps)] with B(C6F5)3 in trifluoroethanol in air gives the complex [Me(bps)Pt-OSiMe(2-C5H4N)2PtMe3]+ [B(OCH2CF3)(C6F5)3]-. The unique binuclear platinum complex is formed via the competitive methyl platinum group cleavage from [PtMe2(bps)] by the acid H[B(OCH2CF3)(C6F5)3] to give the platinum(II) fragment and oxidation by air to give the platinum(IV) fragment. Combination of the two units then gives the binuclear complex which involves a very easy methylsilicon group cleavage reaction. The platinum(II) complexes containing five-membered heterocyclic imidazole ligands show high reactivity to a broad variety of alkyl halides, peroxides, and halogens forming stable platinum(IV) complexes. The dimethylplatinum(II) complex [PtMe2{(mim)2C=CH2}], (mim)2C=CH2 = 1,1-bis(1-methylimidazole-2-yl)ethene reacts with dichloromethane to give the dimethylplatinum(IV) complex [PtCl(CH2Cl)Me2{(mim)2C=CH2}]. The product exists as a mixture of two isomers, the cis isomer as the kinetic product and the trans isomer as the thermodynamic product. The dimethylplatinum(II) complex [PtMe2(DECBP)], DECBP = 4,4'-diethoxycarbonyl- 2-2'-bipyridine], undergoes easy oxidative addition to the corresponding platinum(IV) complexes. The reactions of the complex [PtMe2(DECBP)] with alkyl bromides RCH2Br, which have hydrogen bond donor or acceptor functional groups, result in the formation of stable platinum(IV) complexes. Those complexes self-assemble in the solid state to form supramolecular polymers via the intermolecular OH---O=C, N-H---Br, OH---BrPt, interactions, with other predicted interactions such as the -stacking, and the C(H)---BrPt secondary weak interactions.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this work was the synthesis of N,N'-diphosphanyl-functionalized NHC ligands andtheir coordination chemistry. The novel stable and rigid tridentate N,N'-diphosphanyl-imidazol-2-ylidene was synthesized and experimental and computational information on its stability weregained. It served as a unique platform for the synthesis of novel mono-, di-, tri-, penta-, hexanuclear complexes with the coinage metals (Cu, Ag and Au), exhibiting rare structural features. The mono- and dinuclear complexes with one or two dangling P-donors provided rational access to heterotrinuclear complexes. All these coinage metal complexes have short metal-metalseparations, indicating the presence of d10-d10 interactions, and display excellent luminescentproperties. Partial or complete transmetallation of the homotrinuclear Cu or Ag complexes withPd(0) precursors led to hetero-trinuclear complexes with d10-d10 interactions. In addition to itsbridging behavior, this ligand also showed its chelating behavior in Pd or Cr(III) complexes. Thelatter displayed superior performance in ethylene oligomerization than the Cr(II) complexes andgave mostly oligomers.
Book Synopsis Synthesis and Reactivity of Pt(II) and Pt(IV) Cyclometallated and Tridentate Complexes Derived from Iminophosphines and Phosphinoamides by : Terence James Maguire

This book was released on 2009 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the synthesis and reactivity of platinum(II) and platinum(IV) complexes with mixed donor ligands containing [P, N, C] and [P, N, O] donor sets derived from iminophosphines and phosphinoamides. Chapter 1 introduces the concepts and principles, like hemilability, that influence the formation of stable complexes and how this stabilisation can influence the reactivity of the complex. This is highlighted using aminophosphines and iminophosphines as examples. In order to present the application of these mixed-donor complexes, a comprehensive overview of platinum complex chemistry, including Pt(IV) complexes, trans complexes and cyclometallates, in medicine is given. Chapter 2 reports the coordination chemistry of two types of [P, N, C] donor ligands; iminophosphines HL1-4 and phosphinoamides HL5-7 to generate a novel library of monodentate, bidentate and tridentate cyclometallated Pt(II) species by a variety of methods. Chapter 3 describes the synthesis of novel ionic, monophosphine substituted Pt(II) complexes of [P, N, C] and [P, N, O] ligands. The iminophosphine ([P, N, C] and [P, N, O]) complexes underwent substitution with all three of the phosphines introduced. However, the success of the reaction of the iminolphosphine [P, N, C] complexes depended on the nature of the phosphine used. This leads to the conclusion that substitution reactions of iminolphosphine complexes are influenced by a combination of basicity and steric bulk of the incoming ligand. Chapter 4 reports the oxidation of bidentate and cyclometallated Pt(II) complexes to generate a novel series of Pt(IV) species. Additionally it reports 1H and 31P{1H} NMR investigations into the reduction of Pt(IV) by low molecular weight thiols and finally describes the reaction of the Pt(II) cyclometallates with the same low molecular weight thiols. All compounds synthesised in chapters 2-4 were characterised by elemental analysis, IR, 1H and 31P{1H} NMR spectoscopies. Selected complexes were also analysed using single X-ray crystal analyses and mass spectrometry.
