Abstract:

This thesis will describe the development of a new route to homoallylic amines 9, in four steps from alcohols 1, or acetals 2, which may themselves have to be synthesised. The synthesis is stereoselective, and generates <i>E</i>-9 and <i>Z</i>-9 quite separately, thereby avoiding the sometimes difficult separation of these isomers. Alkenes 3, readily available from alcohols 1 or acetals 2, undergo regio- and stereo-selective 1,3-dipolar cycloadditions with nitrile oxides 4 or nitrones 6. The resulting heterocycles 5 and 7 are reductively cleaved to give β-hydroxy-δ-aminoalkyldiphenylphosphine

Abstract:

The ortho metallation of some aromatic ring systems has been investigated in regard to the influence of several types of phosphorus-centred directing groups upon the reactivity, regioselectivity, and utility in later synthetic elaboration. The metallation step allows derivatisation in several useful ways, offering several routes to the synthesis of novel chiral ditertiary phosphines. Thus, an ortho lithiation of N,N,N',N'-tetramethyl-P-phenylphosphonic diamide (10) led to the interesting primary phosphine, 2-(diphenylphosphino)phenylphosphine (14), after elaboration of the phosphonic diamide d

Abstract:

Two new general synthetic routes to phosphines were developed. The first method described directly converts phosphonates to phosphine oxides using organometallic nucleophiles. This reaction proceeds through a five-coordinate phosphorus intermediate. The second synthetic method uses a deprotonated secondary phosphine oxide for nucleophilic addition to an alkyl halide to form a tertiary phosphine oxide. This reaction proceeds through a standard SN2 mechanism, however in extreme cases a competitive electron transfer reaction was observed. These syntheses were used to make a new dimethyl phosph

Extractants and extraction methodologies play a vital role in many industrial processes, from the concentration of precious metals from ores to the separation of longlived nuclei from radioactive waste as well as the removal of heavy metals from soils and water for remediation. The vast majority of extractants rely on the use of nitrogen, oxygen, sulfur or selenium as Lewis base donor atoms to form coordination complexes with the metal ions of interest. These extractants often make use of the chelate effect and/or the macrocyclic effect in order to form stable complexes. Some of the best known

The success of homogeneous asymmetric catalysis has been attributed to the structure and stereochemistry of the coordinated ligand(s).

The synthesis of P-chiral ligands of this type has been severely hindered by the lack of a general synthetic route allowing the incorporation of phosphorus chirality without the need for separation of diastereomeric precurs

Organophosphorus-mediated reactions are important tools in organic chemistry and are used in the synthesis of highly desirable drug targets, such as morphine.1 A major drawback of traditional phosphorus-mediated reactions is the formation of stoichiometric amounts of phosphine oxide by-products; this renders the product purification difficult and reduces the atom efficiency of these transformations. For these reasons, catalytic variants become desirable; there being two potential strategies to achieve the catalysis; i) redox-driven and ii) redox-neutral.2-4 The redox-driven catalytic cycle req
