Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen bonding is crucial in many chemical and biochemical reactions, as well as in determining material properties. A good insight into the theoretical methods of treating hydrogen bonding is essential for those wishing to model its effects computationally in a wide range of fields involving hydrogen bonding, as well as those wishing to extract the maximal amount of information from experimental data. Theoretical Treatments of Hydrogen Bonding presents the reader with the state of the art of the key theoretical approaches to hydrogen bonding and considers the hydrogen bond from the various aspects. The first five chapters are devoted to the methods used for treating the electronic basis of hydrogen bonding, including a consideration of the electrostatic model, density functional theory and molecular orbital methods. Later chapters consider the dynamics of hydrogen bonds with particular attention to the treatment of proton transfer; manifestations of dynamics as reflected in infrared spectra and nuclear magnetic relaxation are also considered. Hydrogen bonding in liquids and solids such as ferroelectrics are included. The book concludes with an epilogue which discusses the likely development of hydrogen bond computations in very large chemical systems. Theoretical Treatments of Hydrogen Bonding offers the reader a comprehensive view of the current theoretical approaches to hydrogen bonding. It is a valuable presentation of theoretical tools useful to those looking for the most appropriate approach for treating a particular problem involving hydrogen bonding.

Book Synopsis Design, Synthesis, and Reactivity of Bimetallic Complexes of Dimethylplatinum(II) Containing Ditopic Ligands by : Matthew S. McCready
Download or read book Design, Synthesis, and Reactivity of Bimetallic Complexes of Dimethylplatinum(II) Containing Ditopic Ligands written by Matthew S. McCready and published by . This book was released on 2015 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a study of monometallic and bimetallic dimethylplatinum(II) complexes containing ditopic nitrogen donor ligands. This work details the design and synthesis of side-to-side and cofacial arranged ligands and their respective coordination chemistry. The study of the synthesis, characterization and reaction mechanisms of the various dimethylplatinum(II) complexes is outlined in detail with special emphasis focused on the reactivity of the complexes towards oxidative addition. The ditopic ligand 6-dppd, 1,4-di(2-pyridyl)-5,6,7,8,9,10- hexahydrocycloocta[d]pyridazine, was observed to coordinate only a single equivalent of a platinum(II) center. The inability to coordinate a second equivalent, even through an assisted bridging atom, is presumed to be due to a steric clash between the free pyridyl group and the cyclooctyl backbone. In attempts to make heterobimetallic complexes of 6-dppd, the complex [PtMe2(6-dppd)] was observed to react preferentially with mercuric halides by oxidative addition rather than coordination of the mercuric salt in the second coordination site giving complexes [PtXMe2(HgX)(6-dppd)] where X = Br, Cl, OAc. This indicates that the platinum center is actually a better nucleophile than the free pyridyl nitrogen atom. The oxidative addition of solvent dichloromethane was also observed showing the enhancedreactivity of [PtMe2(6-dppd)]. Finally, [PtMe2(6-dppd)] was treated with DCl at low temperature to give the deuteridoplatinum(IV) complex. The deuteridoplatinum(IV) complex reductively eliminates methane in solution and extensive H/D exchange occurs into the CH4 product at low temperature indicating very easy reversibility of the exchange between hydridomethylplatinum(IV) and methaneplatinum(II) complexes. The abstraction of a chloride ligand from [PtClMe(6-dppd)] led to the formation of a complex dimer structure endo, endo-[Pt2Me2(?2-?3-6-dppd)2][OTf]2. This process allowed for the formation of a bimetallic platinum(II) complex which retained the initial stereochemistry. The protonolysis of [PtMe2(6-dppd)] with one equivalent of HOTf led to the generation of methane gas and the concomitant formation of both endo, endo-[Pt2Me2(?2-?3-6-dppd)2][OTf]2 and exo, exo-[Pt2Me2(?2-?3-6-dppd)2][OTf]2. The structures of the exo isomeric clamshell dimers appeared much less sterically hindered in the solid state and were observed experimentally and computationally to be the thermodynamically preferred isomers. The mechanism, selectivity and reversibility of this isomerism process was explored in detail. The reactions of [PtMe2(6-dppd)] with alkyl bromides RCH2Br, which possess hydrogen bonding functionality, result in the formation of stable organoplatinum(IV) complexes capable of forming supramolecular structure via hydrogen bonding. Both intra and inter molecular hydrogen bonding is observed in the formation of supramolecular architectures which self-assemble in the solid state through additional?-stacking and weak secondary interactions. The new anthracene derived ditopic ligands, bpad = N1,N8-bis(pyridin-2- ylmethylene)anthracene-1,8-diamine and adpa = (N, N)-4,4'-(anthracene-1,8-diylbis(ethyne- 2,1-diyl))-bis(N-(pyridin-2-ylmethylene)aniline) were prepared, characterized and used to coordinate dimethylplatinum(II) centers giving cofacial bimetallic complexes of dimethylplatinum(II). [Pt2Me4(bpad)] was shown to degrade over time in solution through a proposed metalation event involving the anthracene backbone. The oxidative addition of a variety of substrates was performed using [Pt2Me4(adpa)] giving stable diplatinum(IV) complexes as characterized by 1H NMR spectroscopy. The new xanthene derived ditopic ligands, ppxda = 2,7-di-tert-butyl-9,9-dimethyl-N4,N5-bis(4-(pyridin-2- ylmethyleneamino)phenyl)-xanthene-4,5-dicarboxamide and pmxda = 2,7-di-tert-butyl-9,9- dimethyl-bis(pyridine-2-ylmethylene)-9H-xanthene-4,5-diamine were prepared characterized and used to ligate two equivalents of a dimethylplatinum(II) center. Diplatinum complexes of both ligands were shown to easily undergo oxidative addition to give the corresponding diplatinum(IV) complexes which adopt the anti orientation. The syn alignment of metal centers was accessible through the abstraction of halides ligands and incorporation of bridging groups as is the case for the pyrazine bridged bimetallic platinum complex [Pt2Me6(C4H4N2)(pmxda)][OSO2CF3]2.

Book Synopsis Reactivity of Dimethylplatinum(II) Complexes by : Muhieddine Ahmad Safa
Download or read book Reactivity of Dimethylplatinum(II) Complexes written by Muhieddine Ahmad Safa and published by . This book was released on 2011 with total page 528 pages. 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.
