Texto completoA series of phosphate esters containing the E.-nitrophenyl moiety as a leaving group were synthesised and their base catalysed hydrolysis and electron impact-induced fragmentations studied. Heterocyclic ester substituents were present in some of the substrates and in-this sense they were considered as models for a nucleotide molecule containing both the 11 energy-rich11 phosphate bond and the nitrogen heterocyclic ring. The relative reactivity of the phosphorus-E,-nitrophenoxide bond was taken as a probe for nitrogen (pyridyl or quinolyl) participation in the substitution reaction. Although the heterocyclic derivatives show that the introduction of the nitrogen centre increases the rate of base catalysed hydrolysis, the reactivity enhancement is. not significant and results probably from polar effects rather than from intra-molecular catalysis. A comparison of the mass spectra of the heterocyclic and carbocyclic analogues, reveal differences which are significant (in the pyridyl substrates) and dramatic (in the quinolyl substrate) with regard to the fragmentation involving the E.-nitrophenoxy radical expulsion and formation of the corresponding phosphorylium ion. Synthetic approaches towards dimethylaryl and dimethyl(arylalkyl) phosphates are discussed. Nucleophilic displacement at the methyl ester carbon, and in particular the oxygen+ nitrogen methyl group transfer in these substrates occurs readily, complicating the synthetic procedures and lowering the stability of products. Dimethyl-(2-pyridylmethyl) phosphate isomerises in water to the zwitterionic N-methylpyridinium derivative via bimolecular methylation. The kinetics of the reaction were studied and no evidence for intra-molecular methyl transfer was obtained. - ii - The isomerisation of dimethyl-(quinolin-8-yl) phosphate in water also provides evidence for the bimolecular methylation. The crystal and molecular structure of dimethyl-(quinolin-8-yl) phosphate was determined and has revealed that the orientation of the CH 3 groups in the crystal provide no indication for the occurrence of methyl transfer in the solid state. The dynamics of the prepared phosphate derivatives studied in solutions were also investigated by means of mass spectrometry. Fragmentation patterns and their relative contributions are presented and discussed. The effect of solvent on the rates of the reaction between trimethyl phosphate and i) pyridine and ii) 4-(dimethylamino)pyridine, was studied at 25 - 65°C using NMR techniques. The solvents used were DzO, CD30D, CD3CN and DzO/CD30D and DzO/CD3CN mixtures. Water (DzO) is the most effective medium for the methyl transfer reaction. We attribute this to the strong hydrogen bonding between water and the departing dimethyl phosphate anion in the transition state. Activation parameters obtained for the reactions in pure solvents confirmed our interpretation of the hydrogen bonding effect operating in the transition state. Fragmentation of S-arylethyl phosphates has been investigated. A novel feature is exhibited by S-arylethyl phosphorochloridates. They easily decompose thermally yielding 1-chloro-2-arylethanes and/or arylethylenes presumably via concerted C-O and P-Cl bond fission involving a phenonium ion intermediate and expulsion of a metaphosphate species.

Texto completoA comparative X-ray analysis study of bis(4-nitrophenyl)-8-quinolinyl phosphate (4), 1-naphthyl-bis(4-nitrophenyl) phosphate (5) and 4-nitrophenyl -8-quinolinyl phosphate (5) was undertaken. In compound (4) donor-acceptor nitrogen-phosphorus interactions change the geometry of the molecule from tetrahedral to quasi trigonal bipyramidal, thus the structure may be considered as an "early stage" of the intramolecular displacement of the 4-ni trophenoxide group. In the diester (6) this interaction is replaced by intermolecular N+ -H...O- hydrogen bonding. In addition the intramolecular non-bonded potential energies of (4) and (5) were calculated and the minimum-energy conformations were compared with those determined by X-ray diffraction. These results confirm the differences observed in the intramolecular interactions operative in (4) and (5). The mass spectra of (4) and (5) are dramatically different with respect to the fragmentation involving expulsion of the 4-nitrophenoxy radical and formation of the corresponding phosphorylitum ion by nitrogen participation. Rate measurements for the base-catalysed hydrolysis of the first P-OPNP linkage show that (4) is not significantly more reactive than (5) and provide no evidence for intramolecular nucleophilic catalysis in the hydrolysis of (4). The crystal and molecular structure of 1-naphthyl acetate (7) was determined. Attempts to grow suitable crystals of 8-quinolinyl acetate (8) failed and therefore its structure could not be elucidated. Possible intramolecular nitrogen - carbonyl carbon interactions operative in (8) could therefore not be established.

A numerical model was constructed to assess the magnitude of organophosphoric acid triester sinks in the Chattahoochee River and to identify concentration patterns downstream of point source discharges. The model was built using WASP5 and supporting software packages. The model simulated mass transport of tri-butyl phosphate, tri (2-butoxyethyl) phosphate, and tri (2-chloroethyl) phosphate within a reach of the river bounded by Buford Dam and Northern Atlanta. Several potential mechanisms for the removal of the phosphate esters from the water column were considered. These were biodegradation, sorption to settling solids, volatilization, and oxidation by free radicals. Of the three phosphate esters considered by the model, tri (2-chloroethyl) phosphate was predicted to be the most resistant to degradation by natural attenuation processes. Tri (2- butoxyethyl) phosphate showed the most potential for degradation in surface waters. Biodegradation and sorption to settling solids were predicted to be the most effective processes for the removal of tri (2-butoxyethyl) phosphate. Concentration patterns at several locations downstream of point source discharges were predicted for the three compounds. Concentration patterns were found to be affected by the diurnal flow variation caused by the operation of two hydroelectric dams within the modeled reach.

Texto completoPhosphate esters play a fundamental role in many biological processes. Unfortunately, the detailed understanding of how monoesters hydrolysis reactions proceed is still subject of debate (this is largely due to the kinetic stability of phosphate monoesters). Modern quantum chemistry methods seems to be a good alternative to elucidate these reaction mechanisms. In this thesis, we have validated the use of quantum calculation (DFT/B3LYP) coupled with a continuum solvation model by studying hydrolysis mechanism of phosphate tri- and diesters. In these cases, the scientific community is unanimous on the fact that they involve pentacovalent phosphorane intermediate or transition state. The same approach is applied to the hydrolysis mechanism of phosphate monoesters. By comparison with the results obtained in the case of the di- and triesters, it is observed that the reactivity of a protonated ester can differ from that of its methylated derivative, for which a phosphorane “intermediate” is occuring
