Abstract:

The dielectric properties of pure low to medium molecular weight poly(ethylene glycol) and poly(propylene glycol) and a variety of their salt complexes have been studied through the measurement of the dielectric permittivity and dielectric loss over a range of frequency and temperature. The major proportion of this study has been concerned with the examination of the nature of the interaction between mercuric chloride and poly(propylene glycol) (PPG). Other salt-poly-ether combinations have also been considered such as cobalt chloride-PPG cadmium chloride-PPG zinc chloride-PPG and ferric chlor

Abstract:

This thesis concerns the preparation and use of diaryliodonium salts. In Project I various unsymmetrical diaryliodonium salts were reacted with three different nucleophiles in order to study the chemoselectivity of the reactions of the salts. The main focus of this project was to gain a deeper understanding of the underlying factors that affect the chemoselectivity in transition metal-free arylation reactions. They were found to be very nucleophile-dependent. Some nucleophiles were very sensitive to electronic effects, whereas others were sensitive to steric factors. Ultimately, some arenes ar

This thesis extends earlier work at the University of Edinburgh aimed at opening up new flowsheets for the hydrometallurgical recovery of base metals using tetradentate ligands which are capable of transporting metal salts {both a metal cation and its attendant anion(s)}. Prototypes were based on salicylaldimine derivatives of diamines, “salen” ligands in which coordination of a metal dication releases the two phenolic protons which are captured by pendant secondary amine groups generating a preorganised dicationic binding site for the anion(s).

Abstract:

This thesis concerns the development of metal-free applications using diaryliodonium salts. The first project describes an arylation protocol of allylic and benzylic alcohols in aqueous media. The method proceeds under mild conditions and the ether products were obtained in moderate to good yields. The methodology was also expanded to include arylation of phenols, giving diaryl ethers in good to excellent yields. In the second project, an arylation method that included a wider range of aliphatic alcohols was developed. The scope of accessible alkyl aryl ethers was studied and included a compar

The preparation and characterisation of 17 previously unreported non-metal cation (NM,C) salts of isolated polyborate anions is reported.

All compounds were characterised by elemental analysis, IR and multinuclear (IH, lIB and ¹³C) NMR spectroscopy. Many compounds were characterised by single-crystal XRD methods (EPSRC service, Southampton University): benzylammonium pentaborate, 1; cyclopropylammonium pentaborate, 2; cyclopentylammonium pentaborate, 3; bis(cyclohexylammonium) heptaborate .B(O

Introduction. Today the environmental pollution with heavy metal salts (HMS) is an important issue, because of their toxic effects and prevalence in different layers of the biosphere.

Urinary bladder(UB) refers to bodies that are subject to double impact of heavy metals. Thus, urine together with its components (including HMS)accumulate and definite time contact with mucous membranes of UB and also the pollutants get into the organhematogenously.
