Annotation:

Setschenow coefficients have been derived from solubility measurements on cyclohexane, benzene, naphthalene, 1-naphthol, 1,5-dihydroxynaphthalene, and anthracene in alkali halide, tetraalkylammonium bromide, and tetraphenylarsonium chloride aqueous solutions at 298.2 K. Single ion Setschenow coefficients have thence been obtained by an assumption involving extrapolation of the tetraalkylammonium bromide results to zero cation volume. Setschenow coefficients for the tetraalkylammonium cations correlate well with a hydrophobicity parameter based on their transfer chemical potentials from water into 1,2-dichloroethane. Keywords: solubilities, aqueous salt solutions, Setschenow coefficients.

AbstractThe electrical conductances of the solutions of four tetraalkylammonium bromide salts (R4NBr), namely tetraethylammonium bromide (Et4NBr), tetrapropylammonium bromide (Pr4NBr), tetrapentylammonium bromide (Pen4NBr) and tetraheptylammonium bromide (Hep4NBr) in 2-ethoxyethanol have been reported at 35, 40, 45 and 50 °C. The conductance data have been analyzed by the 1978 Fuoss conductance–concentration equation in terms of the limiting molar conductance (Λ0), the association constant (KA) and the association diameter (R). The ionic contributions to the limiting molar conductance have also been estimated. Appreciable ionic association was observed for all of these electrolytes in 2-ethoxyethanol. The tetraalkylammonium ions (R4N+) were found to remain scarcely solvated in the present solvent medium within the temperature range investigated here. The solvation of the bromide ion in these tetraalkylammonium bromide is found to be weakened as soon as the ion-pairs are formed. An increase in the temperature results in a lower level of ion-pairing for each of these salts.

The viscosities of the solutions of tetraethylammonium bromide (Et4NBr), tetrapropylammonium bromide (Pr4NBr), tetrabutylammonium bromide (Bu4NBr), tetrapentylammonium bromide (Pen4NBr), and tetraheptylammonium bromide (Hep4NBr) in 2-ethoxyethanol have been reported at 308.15, 313.15, 318.15, and 323.15 K. The viscosity data have been analyzed by the JonesDole equation for the associated electrolytes to evaluate the viscosity B coefficients of the electrolytes. These data have also been analyzed by the transition-state treatment to obtain the contribution of the solutes to the free energy of activation for viscous flow of the solution. The viscosity of the solvent is found to be greatly modified by the presence of all of the tetraalkylammonium ions investigated. Moreover, the tetraalkylammonium ions are found to be unsolvated in 2-ethoxyethanol solutions, they behave neither as structure-breaker nor as structure-maker and the formation of the transition state is made less favorable in their presence.Key words: viscosity, electrolytes, tetraalkylammonium ion, 2-ethoxyethanol, ionic contribution, solvation, transition-state treatment.

Annotation:

The solubilities of tetraalkylammonium dianilinetetraisothiocyanatochromates(III) (alkyl = methyl, ethyl, 1-propyl, and 1-butyl) in water, water - methanol, water - tert-butyl alcohol and water - acetonitrile solutions were measured at 25 °C. The results were used to evaluate the activity coefficients and Gibbs energies of transfer of the saturating salts from water to the mixed systems. The Gibbs energies of transfer of the [Cr(C6H5NH2)2(NCS)4]- ion were obtained by means of known ionic transfer functions for the tetraalkylammonium ions based on the TATB assumption.

Annotation:

Unexpectedly, a Zeise’s salt analogue, the dinuclear, butadiene-bridged complex, trans-eta^2:eta^2-1,3-butadiene-bis(trichloroplatinate(II)) was isolated when [AuCl4] and [PtCl4]2- were reacted together in the presence of the tetrabutylammonium cation. Early observations ruled out the involvement of the gold(III) species in generating the butadiene directly, but it was found to be acting as an oxidising agent facilitating conversion of [PtIICl4]2- to [PtIVCl6]2-, which turned out to be a key observation. Further studies identified the source of the C4 fragment of butadiene as the tetrabutylammonium cation, suggesting a C-H activation, perhaps via some Shilov chemistry, linked perhaps to a Hofmann-like elimination. The reaction is photochemical and proceeds directly from (NBu4)2[PtCl6] in the total absence of gold. A computational study and related literature precedent regarding the excited state of [PtCl6]2- showed the formation of PtIII as well as chlorine radicals, revealing the possibility for radical induction of the reaction. Indeed, PtIII and N-based radicals were found in the electron paramagnetic spectroscopy (EPR) spectrum of an irradiated frozen solution. Given the extrusion of a butadiene fragment from the tetrabutylammonium cation, the possible involvement of Hofmann elimination mechanism was considered. One possibility would be the elimination of butene in the first step with concomitant reduction to PtII leading to a butene analogues of Zeise’s salt, which could then react further to give the observed product. However, this possibility was not supported by the observed unreactivity of [PtCl3(butene)]- (butene = 1-butene or 2-butene) under the prevailing reaction conditions. This led to the proposal of an intermediate complex in which (Bu3N(butene))+ is pi-bound to [PtCl3]-, which was supported by mass spectrometric evidence from a photochemical study. The same reaction was carried out with the [PtCl6]2- salt of other tetraalkylammonium cations (NPr4+ and NPe4+) and alkene-PtII complexes were again found with NPe4+ salts but not with NPr4+ salts. All of these results and observation were collected together to propose an outline mechanism for the reaction. In a totally separate piece of work, some examples of polycatenar 2,5-diphenylpyridine ligands (LH) were prepared and bound to palladium(II) to give complexes with an orthometallated 2-phenylpyridine and an acac co-ligand - [Pd(L)(acac)]. These are analogous to related PtII complexes prepared in the group which were found to be liquid-crystalline and emissive. While some liquid-crystalline examples were prepared, none of the complexes showed evidence for room-temperature triplet emission, which can be a feature of palladium congeners. However, in the related platinum chemistry it was observed that on formation of the complexes with three alkyloxy groups on the metallating phenyl ring, there was a Pt-promoted C-O bond cleavage. The milder conditions required for formation of the palladium meant that the same C-O bond cleavage was not observed here.

Ionic liquids (ILs) are substances composed exclusively of ions that are liquid below 373 K. Room temperature ionic liquids (RTILs) are like ILs but they are also liquid at 298 K. ILs have recently become of interest as a replacement for volatile organic solvents as they generally have little or no vapour pressure and high thermal stabilities meaning that they are more easily contained than traditional solvents. ILs are also of interest in electrochemistry because they can possess large electrochemical windows (EWs) when compared to conventional solvents. This study reports the synthesis of a library of tetraalkylammonium halide salts.

Les comportements cathodiques du graphite d'une part et du platine d'autre part, en milieux organiques aprotiques en presence de cations tetraalkylammonium, sont etudies. La reaction d'insertion des cations conduit a une modification de la structure et des proprietes de ces materiaux. La premiere partie de ce memoire est consacree aux composes d'intercalation du graphite (cig). Le premier chapitre regroupe de maniere detaillee les differents types de composes du graphite, des composes covalents aux cig donneurs et accepteurs, et integre leurs syntheses, leurs proprietes et leurs applications. Le comportement cathodique du graphite en milieu organique est etudie dans le deuxieme chapitre, en presence de differents cations tetraalkylammonium. Des cig de type donneur possedant un fort caractere reducteur et nucleophile sont obtenus. La reactivite de ces composes d'intercalation vis-a-vis du dioxyde de carbone est ensuite envisagee pour conduire a la formation d'un materiau polycarboxyle. Differentes methodes d'analyses chimiques et spectroscopique sont developpees et permettent d'evaluer la modification structurale apportee au graphite. La presence de fonctions carboxyliques sur support solide laisse entrevoir des proprietes d'echange d'ions. Dans cet objectif, la methode de carboxylation a ete etendue a un carbone graphitique, et des tests preliminaires d'extraction de cations metalliques en solution aqueuse ont ete menes sur un tel materiau, ce qui est developpe dans le quatrieme chapitre. Dans une deuxieme partie, le comportement cathodique particulier du platine en milieu organique anhydre et en presence de cations tetraalkylammonium est aborde. L'insertion cathodique des ions tetraalkylammonium dans le metal provoque une modification de la structure du platine. Un complexe organometallique, base sur des clusters de platine, se forme a l'interface du materiau. Son caractere fortement reducteur est montre, et sa reactivite vis-a-vis de composes aromatiques est egalement abordee.

L'oxydation anodique des arylacetates de tetraalkylammonium dans l'acetonitrile s'effectue par un mecanisme concerte ou sequentiel de transfert d'electron et coupure de liaison. L'intervention de l'un ou l'autre mecanisme depend de la structure moleculaire du carboxylate et plus particulierement du caractere electroattracteur ou electrodonneur des substituants sur le noyau aromatique. La chimie homogene suivant le processus de decarboxylation est associee a des reactions de solvolyse et de dimerisation faisant intervenir respectivement des carbocations et des radicaux. La consommation de la moitie de carboxylate par protonation lors des reactions de solvolyse explique la nature monoelectronique du mecanisme en milieu neutre et bielectronique en milieu basique. L'inhibition de la reaction d'oxydation observee est expliquee par un mecanisme de greffage covalent de la surface de l'electrode par de groupements arylmethyles ayant de proprietes electrochimiques semblables a celles des molecules arylmethyle en solution. Selon le potentiel auquel l'oxydation du carboxylate est effectuee, une modification de la concentration superficielle des especes greffees est obtenue.

A presente tese tem como objetivo principal a investigação do processo de intercalação e esfoliação do hexaniobato lamelar em soluções de hidróxidos de tetraalquilamônios e, também, do emprego das partículas do niobato na preparação de materiais híbridos com polissacarídeos. O material de composição H2K2Nb6O17 foi suspenso em soluções aquosas contendo diferentes concentrações dos hidróxidos de tetrametilamônio (TMA+), tetraetilamônio (TEA+) e tetrapropilamônio (TPA+). Após o tempo de reação foram separadas duas frações: o sólido depositado no recipiente e o sobrenadante turvo contendo as partículas não depositadas de características coloidais. Os resultados de difratometria de raios X, análise termogravimétrica, análise elementar, espectroscopia vibracional no infravermelho e Raman mostram que o processo de intercalação é promovido segundo a ordem: TMA+ > TEA+ > TPA+, isto é, a intercalação é facilitada para íons pouco volumosos. Já o processo de esfoliação do hexaniobato é promovido na ordem inversa: TPA+ » TEA+ > TMA+, ou seja, quanto mais volumoso o íon tetraalquilamônio, maior a extensão do processo de separação das lamelas. A formação das partículas cilíndricas, presentes em maior quantidade nas amostras tratadas com soluções de TPA+ e TBA+, é favorecida pelo aumento do tamanho da cadeia carbônica e da concentração das soluções do hidróxido. Além dos processos de intercalação ou esfoliação, observou-se o processo de formação de gel na etapa de remoção de eletrólitos na lavagem dos sólidos depositados. O entumescimento das lamelas empilhadas de hexaniobato é favorecido para amostras intercaladas com íons TEA+; possivelmente esses íons possuem a melhor relação entre hidrofilicidade e tamanho, promovendo a formação de gel. O composto contendo íons TEA+ intercalados no hexaniobato ácido foi empregado na preparação de material híbrido contendo o polissacarídeo quitosana intercalado na matriz inorgânica, com o objetivo de modificar a superfície do hexaniobato para promover a compatibilização com o amido e a formação de nanocompósitos. Filmes de amido desestruturado contendo partículas de hexaniobato foram preparados por casting. Para alcançar alto grau de dispersão da partícula inorgânica no polímero, três tipos de partículas de hexaniobato foram empregadas: (i) partículas esfoliadas com n-butilamina, (ii) partículas altamente hidratadas de TEA+-hexaniobato e (iii) partículas modificadas pela intercalação com quitosana. As técnicas de difratometria de raios X, análise termogravimétrica acoplada à espectrometria de massa, espectroscopia vibracional no infravermelho e microscopia eletrônica de varredura sugerem que nos filmes transparentes e flexíveis obtidos, a matriz lamelar se encontra preferencialmente na forma intercalada. Os resultados preliminares de análise dinâmico-mecânica sugerem a seguinte tendência no comportamento mecânico dos filmes: a adição do hexaniobato torna os filmes de amido mecanicamente mais resistentes e as amostras sem o plastificante glicerol apresentam maior resistência e menor deformação que aquelas com glicerol.
The main aim of this Thesis is the investigation of intercalation and exfoliation processes occurring when the layered material H2K2Nb6O17 is suspended in alkaline solutions containing tetramethylammonium (TMA+), tetraethylammonium (TEA+) or tetrapropylammonium (TPA+) cations, as well as the employment of the hexaniobate particles in the preparation of hybrid materials with polysaccharides. After the reaction using different concentrations of the tetraalkylammonium hydroxide solutions, two fractions were separated: the deposited solid (i.e. the sediment at bottom of the flasks) and the opaque supernatant containing particles with colloidal characteristics. Experimental data from X-ray diffractometry (XRD), mass spectrometry coupled thermogravimetric analyses (TG-MS), elemental analysis, vibrational infrared (IR) and Raman spectroscopies show that intercalation reaction is promoted in the order TMA+ > TEA+ > TPA+ while exfoliation process is facilitated in the inverse order: TPA+ » TEA+ > TMA+. Development of particles with stick-like shapes is observed when H2K2Nb6O17 is kept mainly in the solutions containing the larger TPA+ and TBA+ ions. Samples containing intercalated TEA+ ions form a gel-like system when washed to remove the non-intercalated ions dissolved in water. Experimental data suggest that the gel phase constituted by long-range swelled particles. This fact was interpreted as a consequence of the intermediate characteristics (surface polarity and ion radius) of the TEA+ ions compared to the others ions investigated in this study. The hexaniobate material intercalated with TEA+ ions was used to prepare a hybrid material having the chitosan polymer intercalated into the inorganic matrix in order to compatibilize the hexaniobate particles with starch and a nanocomposite formation. The study of the films of starch-niobate showed that the matrix is in the intercalation form preferentially, even using different exfoliation agents and modification species (n-butylamine, TEAOH and chitosan). Films of destructured starch having hexaniobate particles were prepared by casting method. In order to reach a high level of inorganic particles dispersed in the polymer, three kinds of hexaniobate particles were used: (i) particles exfoliated with n-butylamine, (ii) hydrated particles of TEA+-hexaniobate and (iii) hexaniobate particles intercalated with chitosan. XRD, TG-MS, IR, and scanning electron microscopy (SEM) techniques suggest that hexaniobate particles are mainly in the intercalated form in the transparent and flexible obtained starch films. Preliminary dynamic mechanical analysis data indicate the following general tendency in the mechanic characteristics of the films: niobate particles make the starch films more resistant and the samples without the glycerol plasticizer present higher resistance and lower deformation than the films with glycerol.

These salts were studied using various techniques, including infrared and electronic absorption spectracopies, temperature -varied SQUID and DC-conductivity measurements. Salts with siniclar composition gave very similar infrared spectra. Solution electronic absorption spectra could be use to determine quantitatively the total content of Q and Q- Solid-State electronic absorption spectra suggested Q-(Q- and Q) anions (anions and molecules ) associate to polymers in the salts are diamagnetic and the complex salts are weakly , consistent with the association of the acceptors in the salts.

Physical properties of these crystals were also measured, including infrared spectra , ultraviolet-visible spectra , SQUID magnetic susceptibilities , and D C-conductivities measurements. The crystals and molecular structure of [tet- ramethylammonium][Qimnt]2 and [tetraethylammonium][Qimnt]2 have been determined by the single-crystal X-ray diffraction analysis. Both complexs are segregated stacked and dimer structure. All the salts behave as semi-conductor,the D C- conductivities range from -3 order to -8 order。

Synthesis of cyclodextrin derivatives for practical applications Abstract The first part of this PhD thesis is focused on the synthesis of a series of monosubstituted tetraalkylammonium cyclodextrin (CD) derivatives. The emphasis was placed on the possible applicability of the synthetic process to multigram or even industrial scale. Monotosylation of the native cyclodextrins (-, -, -) on the primary side of the macrocycle afforded the starting materials. Derivatives with one cationic group were prepared by the reaction with aqueous trimethylamine. The reaction of the mono-Ts-CD with neat N,N,N'-trimethylethane-1,2-diamine or N,N,N'-trimethylpropane-1,3-diamine and subsequent methylation led to derivatives with the substituent bearing two cationic groups (PEMEDA- and PEMPDA-β-CD). Analogs bearing a moiety with three tetraalkylammonium sites were synthesized by reaction of mono-Ts-CD with bis(3-aminopropyl)amine with subsequent methylation. 1,3-Dipolar cycloaddition of mono-6- azido--CD with diaminoacetylenes followed by methylation led to analogs with a avariable distance of the charged substituent from the CD core. Majority of the presented reactions are straightforward, relatively high-yielding and the workup does not require chromatographic steps. The second part of the work is dealing with the...
