Resumen

Iodo-bridged platinum(II) dimers, [Pt(L)I2]2 with ligands (L) containing nitrogen as the donor atom, have been synthesized from the reactions of cis-[Pt(L)2I2] with perchloric acid. The dimers can be cleaved in aqueous media by a second nitrogen ligand to produce isometrically pure cis-[Pt(L)(L′)I2].These compounds can finally be converted to the chloro or carboxylato compounds by precipitating the iodo ligands with a silver salt and adding KCl or a carboxylate salt. Several compounds of the types cis-[Pt(L)(L′)Cl2] and cis-[Pt(L)(L′)(dicarboxylate)] were thus prepared. A few dimers of the type [(L)(L′)Pt(tetra-carboxylate)Pt(L)(L′)] were also synthesized.

Resumen

This manuscript focuses on the reactions of 4-phosphorylated 5-hydroxyhexa-2,3-dienoates with protected or unprotected hydroxy groups involving 5-endo-trig cyclizations. Reactions with electrophiles result in mixtures of the 2,5-dihydro-1,2-oxaphosphole-5-carboxylates and the 5-phosphorylfuran- 2(5H)-ones by competitive electrophilic cyclization due to the neighboring phosphonate (phosphine oxide) and the carboxylate groups participation. 4-Phosphorylated 5-hydroxyhexa-2,3-dienoates were smoothly transformed into the corresponding 4-phosphoryl-2,5-dihydrofuran-2-carboxylates by using 5 mol % of a silver salt as a catalyst in the 5-endo-trig cycloisomerization reaction.

Resumen

Potassium phthalide-3-carboxylate (3-oxo-1,3-dihydroisobenzofuran-1- carboxylate ) decarboxylates readily in dimethyl sulfoxide at 145°, and the intermediate phthalidyl anion is efficiently trapped by α,β - unsaturated ketones. The major 1,4-addition product is accompanied by smaller amounts of an isomeric product formed by subsequent cyclization and rearrangement, and sometimes traces of a 1 : 2 1,4-addition product. The caesium salt gives slightly more cyclized product, and the lithium salt undergoes very slow decarboxylation. The synthetic usefulness of the salt decarboxylation is compared with that of the free acid.

Resumen

Imidazole-containing compounds exhibit a myriad of pharmacological activities. Two tetrachloridozincate salts of 4-carboxy-1H-imidazol-3-ium, ImHCO2H+, are reported. Bis(4-carboxy-1H-imidazol-3-ium) tetrachloridozincate monohydrate, (C4H5N2O2)2[ZnCl4]·H2O, (I), crystallizes as a monohydrate salt, while bis(4-carboxy-1H-imidazol-3-ium) tetrachloridozincate bis(1H-imidazol-3-ium-4-carboxylato) monohydrate, (C4H5N2O2)2[ZnCl4]·2C4H4N2O2·H2O, (II), is a co-crystal salt with six residues: two ImHCO2H+cations, two formula units of the zwitterionic 1H-imidazol-3-ium-4-carboxylate, ImHCO2, one tetrachloridozincate anion and one water molecule disordered over two sites in a 0.60 (4):0.40 (4) ratio. The geometric parameters of the ImHCO2H+and the ImHCO2moieties are the same within the standard uncertainties of the measurements. Both compounds exhibit extensive hydrogen bonding, including involvement of the tetrachloridozincate anion, resulting in interconnected chains of anions joined by water molecules.

Resumen

In the title salt, {[Li(C2H5NO2)2]ClO4} n , the Li+ cation is coordinated by four carboxylate oxygen atoms of the glycine molecules with a distorted tetrahedral geometry. The glycine exists in a zwitterionic form with protonated amino and deprotonated carboxylate groups. In the crystalline state, the title salt is primarily stabilized by intermolecular N—H...O and Cα—H...O interactions which interconnect various units. Hirshfeld surface analysis indicates that the intermolecular H...O/O...H interactions are the most important contributors to the crystal packing.

Resumen

Thesis (MSc (Chemistry and Polymer Science))--University of Stellenbosch, 2009.
ENGLISH ABSTRACT: This thesis reports an in-depth investigation of the intermolecular interaction motifs in secondary, primary and ammonium carboxylate salts. The investigation was conducted using the Cambridge Structural Database (CSD), together with a systematic steric-specific experimental study. The tendency in the literature has been to analyse organic salt crystal structures in terms of hydrogen bonding patterns, almost ignoring cation-anion interactions. This study focuses on the cation-anion interactions in secondary, primary and ammonium carboxylate salts, which have a direct effect on the formation of specific structural motifs. The ideas of ring-stacking and ring-laddering, which arise from the tendency of cations and anions to arrange themselves so as to maximise electrostatic interactions, have been applied to ammonium carboxylate salts. An extensive survey of organic ammonium carboxylate salt structures in the CSD has been carried out. The structural motifs in ammonium carboxylates were investigated, and a set of predictive rules for the pattern of intermolecular interactions in these salts was developed. Using these results, the formation of ring-stacking or ring-laddering in primary ammonium carboxylate salts can be predicted. The results from the CSD survey are discussed in Chapter 3. An experimental study has been carried out, which complements the results obtained from the CSD survey. The experimental study formed 19 novel ammonium carboxylate salts, of which 2 formed hydrates and 2 co-crystals of salts. The experimental results confirm what was found in the CSD survey, and this is discussed in Chapter 4. This study has found that the principle of ring-stacking and ring-laddering can be applied in a general form to the crystal structures of organic ammonium carboxylate salts. The size of the cation and the anion in these salts has a significant effect on the formation of structural motifs in the solid state. Interactions between cation and anion substituents also play an important role in the formation of particular structural motifs in ammonium carboxylate salts.
AFRIKAANSE OPSOMMING: In hierdie tesis word die intermolekulêre interaksie motiewe in die sekondêre, primêre en ammonium karbosilaat soute in-diepte ondersoek. Die studie is gedoen met behulp van die Cambridge Strukturele Databasis (CSD), saam met ‟n sistematiese steriesspesifieke eksperimentele studie. Die neiging in die literatuur is om organiese sout kristal strukture in terme van waterstofbindings patrone te analiseer sonder om katioon-anioon interaksies in ag te neem. Die studie fokus juis op hierdie katioon-anioon interaksies tussen sekondêre, primêre en ammonium karbosilaat soute wat ‟n direkte effek het op die vorming van spesifieke strukturele motiewe naamlik „ring-stacking‟ en „ring-laddering‟ wat hul oorsprong kry vanaf die neiging van katione en anione om hulself op so ‟n wyse te rangskik sodat die elektrostatiese interaksies ‟n maksimum kan bereik, op die ammonium karboksilaat soute. ‟n Volledige ondersoek van ammonium karboksilaat soute in die CSD is gedoen. Die strukturele motiewe in ammonium karboksilaat is ondersoek, en ‟n stel reels wat die patrone van intermolekulêre interaksies in hierdie soute voorspelis ontwikkel. Hierdie resultate kan gebruik word om die vorming van „ring-stacking‟ en „ring-laddering‟ in primêre ammonium karbosilaat soute te voorspel. Die resultate van die CSD ondersoek word bespreek in Hoofstuk 3. ‟n Eksperimentele studie is uitgevoer en die resultate hiervan komplimenteer die resultate van die CSD ondersoek. In die eksperimentele studie is 19 nuwe ammonium karboksilaat soute gekristaliseer, waarvan 2 hidraat-soute en 2 ko-kristal-van-soute is. Die eksperimentele resultate bevestig die bevindings van die CSD ondersoek, en dit word bespreek in Hoofstuk 4. Hierdie studie het gevind dat die beginsel van „ring-stacking‟ en „ring-laddering‟ kan in „n algemene vorm in die kristal strukture van organiese ammonium karboksilaat soute toegepas word. Die grootte van die katioon en anion in hierdie soute het ‟n beduidende effek op die vorming van strukturele motiewe in die vaste toestand. Interaksie tussen die katioon en anioon substituente speel „n belangrike rol in die vorming van spesifieke motiewe in ammonium karbosilaat soute.

Resumen

The MixAlco process, a proprietary technology owned by Texas A&M University, converts biomass (e.g., municipal solid waste, sewage sludge, paper, agricultural residues, and energy crops) into usable chemicals (e.g., acetic acid) and fuels (e.g., ethanol). Historically, calcium carbonate has been used as the buffer. Recently, it was found that using ammonium bicarbonate as the buffering agent enhances the fermentation conversion. In this case, fermentation broth contains ammonium salts (e.g., ammonium acetate, propionate, butyrate, pentanoate). Therefore, the downstream processing steps (including extraction, purification, esterification, and product separation) must be compatible with the ammonium carboxylate salts formed in the fermentation. This research focuses on converting fermentation broth carboxylate salts into their corresponding acids via "acid springing." Reactive extraction and thermal conversion (distillation) are crucial parts of the acid springing process. Because the components of the fermentation broth are over 80% ammonium acetate and 20% other ammonium carboxylate salts (ammonium propionate, butyrate, pentanoate, etc.), all the initial experiments in this study were performed using reagentgrade ammonium acetate to simplify the reaction. Later, actual fermentation broth was employed. The primary objective of this study was to provide the optimal operating conditions to make the downstream processing steps of the MixAlco process compatible with ammonium carboxylate salts formed in the fermentation. The optimal initial concentration for reactive extraction should be 150-200 g/L and the volume ratio of aqueous phase and extractant should be 1:1. The distribution coefficient reaches the maximum value when the concentration of TOA is 20% (vol %) in n-octanol. The batch distillation study shows that there are two reaction stages: (1) water leaves the system at 100-106 °C and (2) the acid-amine complex decomposes at 160-180 °C.

Resumen

L'elaboration de nouveaux materiaux polymeres pour l'electro-optique utilises par exemple dans les ecrans de television, les cameras, etc a motive ce travail. Dans ce cadre, des complexes derives de ligands de type carboxylate aliphatique et aromatique avec des metaux a sous-couches electroniques pleines (calcium, magnesium, zinc et cadmium) ont ete synthetises. Certains de ces composes possedent, a l'extremite de chaque chaine aliphatique du carboxylate, des fonctions acrylates pour permettre leur polymerisation. L'etude des proprietes mesomorphes de ces metallocarboxylates montre, d'une part, la grande diversite des structures des mesophases selon la nature du metal, qui serait attribuee a des geometries de coordination differentes. D'autre part, la presence d'un noyau aromatique ainsi que l'augmentation du nombre de ses substituants, semblent favoriser le caractere mesomorphe en particulier de type colonnaire dans le cas des dialcoxybenzoates de zinc et magnesium. Les complexes avec les metaux a sous couches electroniques pleines et possedant des fonctions acrylate sont aisement photopolymerises, ce qui n'est pas le cas des carboxylate de cuivre. Deux parametres semblent entrer en competition lors de la polymerisation d'un compose pur dans sa mesophase colonnaire: l'ordre et la mobilite anisotrope du monomere. La photopolymerisation de gels constitues de 10 ou 50% de monoalcoxybenzoates metalliques non polymerisables et 90 a 50% d'un mesogene nematique organique possedant des fonctions acrylates a egalement ete effectuee, mais cette etude demande d'etre approfondie. Les mesures d'indices de refraction et de birefringence des polymeres ainsi obtenus ont ete mesures. Ces mesures ne revelent pas une forte influence des atomes metalliques sur les proprietes optiques. Enfin, l'homopolymerisation d'un metallomesogene colonnaire dans son etat pur, a ete effectuee pour la premiere fois, au cours de ce travail

A physical gel is a substantially dilute network in which junctions can break and recombine due to thermal fluctuation, i.e., the junctions have the finite lifetime. When in the steady-state, it exhibits no flow. In general, reversible gels are formed by polymers, with weak attractions like hydrogen bonds, for example, biopolymers gelatin and agar. Typically, the surfactant gel is referred to the cationic surfactant/water system involving cetyl-trimethylammonium bromide (CTAB). However, it is generally believed that CTAB surfactant molecules assemble into worm-like micelles in aqueous media and yield a transient network structure due to the topological entanglement of the micelles. As a result, it is more like a viscoelastic solution rather than a jelly-like gel. In this work, the gelation of a surfactant solution involving anionic surfactant/water system including sodium laurate (NaL) and sodium tetradecanoate (NaM) is explored by rheological properties measurement and differential scanning calorimetry. The surfactant solution transforms from a transparent liquid to a white opaque gel upon lowering the temperature and vice versa. The characteristics of the surfactant gel is confirmed by the fact that the storage module G”is greater than the loss module G”. In addition to investigate the gelling mechanism such as the nature of associative bonds and microscopic structure, the effects of surfactant concentration, alkyl chain length, and salt addition on the gel properties are studied as well.

Resumen

The MixAlco process uses an anaerobic, mixed-culture fermentation to convert lignocellulosic biomass to carboxylate salts. The fermentation broth must be clarified so that only carboxylate salts, water, and minimal impurities remain. Carboxylate salts are concentrated by evaporation and thermally decomposed into ketones. The ketones can then be chemically converted to a wide variety of chemicals and fuels. The presence of excess lime in the thermal decomposition step reduced product yield. Mixtures of calcium carboxylate salts were thermally decomposed at 450 degrees C. Low lime-to-salt ratios (g Ca(OH)2/g salt) of 0.00134 and less had a negligible effect on ketone yield. In contrast, salts with higher lime-to-salt ratios of 0.00461, 0.0190, and 0.272 showed 3.5, 4.6, and 9.4% loss in ketone yield, respectively. These losses were caused primarily by increases in tars and heavy oils; however, a three-fold increase in hydrocarbon production occurred as well. To predict ketone product distribution, a random-pairing and a Gibbs free energy minimization model were applied to thermal decompositions of mixed calcium and sodium carboxylate salts. Random pairing appears to better predict ketone product composition. For sodium and calcium acetate, two types of mixed sodium carboxylate salts, and two types of mixed calcium carboxylate salts, activation energy (EA) was determined using three isoconversional methods. For each salt type, EA varied significantly with conversion. The average EA for sodium and calcium acetate was 226.65 and 556.75 kJ/mol, respectively. The average EA for the two mixed sodium carboxylate salts were 195.61, and 218.18 kJ/mol. The average EA for the two mixed calcium carboxylate salts were 232.78, and 176.55 kJ/mol. In addition, three functions of conversion were employed to see which one best modeled the experimental data. The Sestak-Berggren model was the best overall. Possible reactor designs and configurations that address the challenges associated with the continuous thermal decomposition of carboxylate salts are also presented and discussed. Methods of fermentation broth clarification were tested. Flocculation showed little improvement in broth purity. Coagulation yielded broth of 93.23% purity. Filtration using pore sizes from 1 micrometer to 240 Daltons increased broth purity (90.79 to 98.33%) with decreasing pore size.

Resumen

Aromatic stacked salt bridges are increasingly observed to play an important role in biology, suggesting that the two separate weak interactions cooperate with each other to mediate molecular recognition in a biological solution. In this thesis an in depth study was carried out in attempt to find the contribution of the guanidinium-carboxylate-aromatic triad in biological systems. Two different small molecule systems are used to carry out the study. From the results of the two chapters I proposed here that stacking aromatic ring enhances the salt bridge through desolvation effect. This hypothesis was also tested in a protein-protein interaction (Grb2 SH3 domain/SOS interaction). The most ideal peptide inhibitor cannot be obtained due to the synthetic difficulties. Limited result showed that increasing the hydrophobic area of the hot spot in this protein-protein interaction enhances the interaction. In researching the guanidinium-carboxylate-aromatic triad, we were inspired to study the pre-organization effect of 1,3,5-triethyl-2,4,6-trisubstituted benzene template. A computational and literature study done in this thesis showed that the installation of ethyl or methyl groups at 1,3,5 positions leads to consistent increases in binding affinity relative to unsubstituted hosts, but the amount of increase is non-trivial and varies with different substitutes. The installation of ethyl or methyl groups at 1,3,5 positions leads to consistent but relatively small increases in binding affinity relative to unsubstituted hosts.

Abstract Amide functionalized of N-heterocyclic carbene complexes of silver(I) and gold(I) were prepared. All the complexes prepared are thermotropic liquid crystals. These compounds also exhibit gellating properties in DMSO. Porous donut shaped solids composed of fibers of 260nm thickness were obtained from MeOH solvent. Interesting thermochromism phenomenon occurs in the phase transition. A helical structure were proposed. Liquid crystalline zinc(II) and copper(II) complexes of carboxylates containing imidazolium cations were prepared. Liquid crystalline behaviors of these compounds are different from those simple carboxylate compounds, because of the zwitter ionic properties of the ligands we used. The Cu(II) series trends to form lamellar mesophase instead of discotic mesophase observed in the carboxylate compouns.

Resumen

Vitamin K-dependent carboxylase activity has been detected in human andbovine vessel wall. Studies comparingthe carboxylases from liver and vessel wall revealed that the enzyme systems may be regarded as isoenzymes withwidely different substrate specificities. The carboxylated product of vessel wall carboxylase has not yet been identified, but it seems plausible that it will be found amongst the Gla-containing proteins which are abundantly present in calcified atherosclerotic plaques (Gla= gammacarboxyglutamicacid, the abnormal amino acid formed by vitamin K-dependent carboxylase). Therefore we have started to characterize the protein constituents of hardened atherosclerotic plaques.The calcified areas from human aortae were solubilized in EDTA and the proteins extracted were partly purified by batch-wise adsorption onto QAE and elution with high salt. The crudeplaque-extract did not contain prothrombin, factor X or protein C. This excludes the possibility that Gla-containing coagulation factors are bound non-specifically from blood. Osteocalcin accounted for 20% of the total amount of protein-bound Gla-residues.Another Gla-containing protein waspurified from the crude plaque-extract by employing high performance liquid chromatography (HPLC). Gel filtration yielded a Gla-rich protein with anapparent Mr of 25 kD. In vitro boththe crude plaque-extract and the purified Gla-containing protein strongly inhibited the precipitation of calcium phosphate and calcium carbonate. A similar effect was not found with humanserum albumin nor with a thermallydecarboxylated plaque-extract. If also in vivo the Gla-containing proteinsproduced by vessel wall carboxylase prevent the precipitation of calcium salts remains to be investigated.

Resumen

During the last three years, we could detect hereditary quantitative protein C (PC) deficiency in 43 patients belonging to 18 families. In those defects type I without oral anticoagulant treatment, the values of PC measured either by an ELISA method (PC:Ag) or by a chronometric functional assay were very closed and well correlated. (Results expressed in % of normal pooled plasmas PC:Ag m=44,l %, SD = 15,3 ; PC : activity m = 49,5, SD = 13,5 - correlation r = 0,82). In a 32 year#old man with a severe thrombo-embolic disease and in 11 related people, we could diagnose a hereditary qualitative PC deficiency type II, because of a discrepancy between normal PC:Ag levels (m = 105 %, SD = 20,3, range = 78-143) and low PC anticoagulant activities (m = 46 %, SD = 9,5, range = 30-60). FunctionalpC studies included assays, with or without preliminary adsorption on baryum citrate or aluminium hydroxide, with various PC activators (thrombin, PROTAC venom), in chronometric and amidolytic assays.(Normal protein S levelswere first tested).As shown by those results, PC activity is normal in amidolytic assays even after preliminary adsorption whatever the activation is. On the contrary, the PC anticoagulant activity is reduced in any technique. We can conclude that the activation is normal. Crossed immunoelectrophoresis (CIE) with or without calcium showed normal migration as compared to controls. Normal adsorption on insoluble salts and normal Ca-binding in CIE allow us to say that the abnormal PC is not completely acarboxylated. As amidolytic assays (normal in patients) do not assess the ability of activated PC to interact with protein S (PS) and phospholipids via calcium, 3 hypothesis can explain the functional abnormality:- abnormal binding to PS- abnormal binding to phospholipids due to partially carboxylated glutamic acids (which would be sufficient to promote adsorption)- defective inhibition of Va and Villa because a conformational change allowing only hydrolysis of little synthetic peptides.
