Abstract:

The synthesis and reactivity of a number of mixed transition metal-aluminium and σ-alane complexes are detailed in this thesis. Chapter III reports on the formation and structural characterisation of N,N'-chelated aluminium dihalide precursors featuring amidinate and guanidinate substituents. These precursors of the type RC(R'N)<sub>2</sub>AlX<sub>2</sub> (R = <sup>i</sup>Pr<sub>2</sub>N or Ph; R' = Cy or <sup>i</sup>Pr or Dipp; X = hal), readily react with Na[CpFe(CO)<sub>2</sub>] via salt elimination to form the corresponding mixed iron-aluminium complexes CpFe(CO)2[(X)Al(NR')2CR] which have

Abstract:

The work presented in this thesis describes the synthesis, structure and stability of a range of halido, hydrido and heterocyclic complexes of the group 13 elements. The underlying theme is the synthesis of low valent group 13 complexes. The work upon this subject is divided into five chapters. Chapter 1 provides a general introduction to the members of group 13 and to low oxidation state group 13 halide chemistry. The history of binary group 13 metal trihydride complexes and the reasons behind their inherent instability are also discussed. Chapter 2 details the use of a stable nucleophilic N-

The work presented in this thesis is concerned with synthetic and computational studies of low coordinate transition metal complexes of boron. New symmetrically bridged boryl complexes of iron and manganese have been prepared and characterised. Information obtained from spectroscopic and structural analyses, together with Density Functional theoretical studies, has been used to investigate the nature of the metal-boron bonds in these complexes. Development of the chemistry of related terminal analogues has also been undertaken. The M-B bonds present in these molecules can be considered mainly

Reaction of the triaza macrocycles RMe2-tacn (R = Me, Bz) with the Group 13 chlorides MCl3 gives the solvent free distorted octahedral adducts [MCl3(RMe2-tacn)] (M = Al, Ga, In). Reaction of the trichloro complexes with aqueous KF at room temperature yields the hydrated complexes [MF3(RMe2-tacn)]∙xH2O. The trifluoro complexes are formed in high yield, are stable under a range of conditions, and display significant H-bonding interactions between the coordinated fluoride ligands and the crystallised water molecules in the solid state, confirmed crystallographically.

Abstract:

Supercritical fluid electrodeposition is a new technique being developed that aims to deposit technologically important p-block materials at the nanoscale. This requires significant synthetic effort in precursor development, and investigations into fundamental p-block coordination chemistries, primarily through the use of neutral phosphine and arsine ligands, have been undertaken to aid the design process. The compounds synthesised have been characterised by microanalysis, IR spectroscopy and multinuclear NMR spectroscopy (1H, 11B, 19F, 31P{1H}, 27Al and 119Sn, where appropriate), while single

Abstract:

Au début de ces travaux, peu d’études avaient été faites sur la complexation des carbènes N-hétérocycliques avec des métaux oxophiles, électropositifs et à hauts degrés d’oxydation tel que les métaux du groupe 13. L’optimisation de voies de synthèse a permis d’étendre le nombre de complexes de types NHC-MIII (M = aluminium, gallium et indium), ainsi qu’à des complexes cationiques. L’association de ces précurseurs avec des NHCs plus encombrés a permis l’observation de réactivités sans précédent (complexes anormaux, paires de Lewis frustrées, dicarbènes N-hétérocycliques).

Abstract:

This work is mainly concentrated on the development of new versatile ligand based on N,N’-disubstituted-1,8-diaminonaphthalene (1,8-DAN) for main group chemistry. Therefore, our initial efforts were made on the design of new ligand scaffold by using 1,8-DAN. Following that, new ligand family supported by 1,8-DAN was applied as ligands to main group elements (B, Al, In, Ga, and C). Furthermore, six-membered ring carbenes which are derived from the reaction between N,N’-disubstituted-1,8-diaminonaphthalene and carbon are also investigated. In addition, the stable carbenes were implied as a new l

GaCl3 can react with macrocyclic thio- and seleno-ethers to give complexes with coordination numbers and geometries that were previously not accessible by using acyclic chalcogenoether ligands.

GaCl3 was also found to promote the one and two electron oxidation of [8]aneSe2 to [{[8]aneSe2}2][GaCl4]2 and [{[8]aneSe2Cl}][GaCl4]. The coordination complexes [GaCl3(nBu2E)] and (GaCl3)2{nBuE(

Abstract:

The first example of an N,N'-chelated [beta]-diketiminato phosphenium salt has been isolated by careful tuning of both the ligand architecture and the electronic characteristics of the phosphorus containing moiety. Using a two-electron reduction approach, the first example of a phosphinidene valence isomer has been isolated and structurally characterized. The mechanism of formation of this valence isomer was elucidated via Density Functional Theory (DFT) calculations. These calculations revealed that the formation of this valence isomer involves the intermediacy of a triplet diradical. In

It was observed that the coordination behavior of the amine phenolates and the stability of the resulting metal complexes were closely related to the flexibility of the ligand, the type and spatial organization of the donor atoms, as well as to the elec
