Abstract:
The development of efficient and low-cost catalytic systems is important for the replacement of robust noble metal complexes. The synthesis and application of a stable, phosphine-free, water-soluble cyclopentadienone iron tricarbonyl complex in the reduction of polarized double bonds in pure water is reported. In the presence of cationic bifunctional iron complexes, a variety of alcohols and amines were prepared in good yields under mild reaction conditions.

Full text
Abstract:
The PhD project focused on the synthesis and catalytic applications of (cyclopentadienone)iron complexes in reactions involving hydrogen transfer. The manuscript is divided into five chapters, and after a rather comprehensive review on the state of the art in chapter 1, the thesis describes, in the remaining four chapters, the original achievements of the PhD candidate. In particular, chapter 2 describes the applications of highly active [bis(hexamethylene)cyclopentadienone]iron tricarbonyl pre-catalyst for the reduction of imine bonds under transfer hydrogenation conditions and for the reductive amination of carbonyl compounds. In chapter 3, the application of the above mentioned pre-catalyst to alcohol amination reactions via a hydrogen borrowing mechanism is discussed. Chapter 4 deals with enantioselective ketone hydrogenations using chiral (cyclopentadienone)iron complexes containing a stereogenic plane (prepared in racemic form and resolved by chiral HPLC), and with the synthesis of chiral macrocyclic (cyclopentadienone)iron complexes, putatively more suited for the transfer of the chiral information from the catalyst to the substrate. Finally, Chapter 5 describes the immobilization of (cyclopentadienone)iron complexes into a solid support, namely Metal Organic Frameworks (MOFs), to realize an active heterogeneous (cyclopentadienone)iron catalyst for catalyst recycling in batch hydrogenation reactions and potential applications in flow processes.

Abstract:
The synthesis of (cyclopentadienone)iron tricarbonyl complexes and the application of said complexes to the catalysis of ‘hydrogen borrowing’ reactions between amines and alcohols has been studied. A family of analogous (cyclopentadienone)iron tricarbonyl complexes were synthesised and used in ‘hydrogen borrowing’ with aniline and analogous alcohol reagents comprising increasing carbon chain length, in an attempt to gain more understanding of the effect of altering the electron environment of the hydroxy group of the active iron catalysts generated from the synthesised (cyclopentadienone)iron tricarbonyl complexes. Utilising an alternative set of reaction conditions, the scope of the ‘hydrogen borrowing’ methodology was extended to include amines derived from piperidine, benzylamine and other aliphatic amines. The incorporation of additional functionality (e.g. alkene or alkyne groups) into the product amines was also found to be an option of the new methodology. The synthesis of novel asymmetric (cyclopentadienone)iron tricarbonyl complexes was also attempted and a novel application of Ru(II)/TsDPEN hydrogen transfer catalysts was also discovered.

Abstract:
Next to conventional solar panels that harvest direct sunlight, p-type dye-sensitized solar cells (DSSCs) have been developed, which are able to harvest diffuse sunlight. Due to unwanted charge recombination events p-type DSSCs exhibit low power conversion efficiencies (PCEs). Previous research has shown that dye-redox mediator (RM) interactions can prevent these recombination events, resulting in higher PCEs. It is unknown how the nature of dye-RM interactions affects the PCEs of pseudorotaxane-based solar cells. In this research this correlation is investigated by comparing one macrocycle, the 3-NDI, in combination with the three dyes that contains a recognition sites. 2D-DOSY-NMR experiments have been conducted to evaluate the diffusion constants (LogD) of the three couple. The research project has been stopped due to the coronavirus pandemic. The continuation of this thesis would have been to synthesize a dye on the basis of the data obtained from the diffusion tests and attempt the construction of a solar cell to then evaluate its effectiveness. During my training period I synthetized new Fe(0) cyclopentadienone compounds bearing a N-Heterocyclic Carbene ligand. The aim of the thesis was to achieve water solubility by modifications of the cyclopentadienone ligand. These new complexes have been modified using a sulfonation reaction, replacing an hydroxyl with a sulfate group, on the alkyl backbone of the cyclopentadienone ligand. All the complexes were characterized with IR, ESI-MS and NMR spectroscopy, and a new Fe(0) cyclopentadienone complex, involved as an intermediate, was obtained as a single crystal and was characterized also with X-Ray spectroscopy.

Abstract:
ABSTRACT Solventless reactions of substituted cyclopentadienyl metal carbonyls of iron and ruthenium with electron donor ligands have been carried out. The reactions between CpFe(CO)2I and a range of phosphine ligands occurred in melt phase and yielded two typical compounds : salt product, [CpFe(CO)2PR3]I, and non-salt product, CpFe(CO)PR3I with the salt product being predominant. The complex [CpFe(CO)2]2 was used to catalyze these reactions. The progress of the reactions was followed by 1H NMR spectroscopy. The characterization of products correlates well with the products obtained when working in solution medium. The presence of a Me substituent on the Cp ring was found to favour the salt product formation but generally led to lower rates of reaction. Solventless reactions between RCpRu(CO)2I (R = H, Me) and solid phosphine ligands were also carried out. It has been observed that the ruthenium complexes were less reactive compared with their iron analogues but led to the same types of products namely salt and non-salt. The phosphite ligands were found to be less reactive than their phosphine analogues. In fact, the solventless reactions between RCpM(CO)2I (R = H, Me; M = Fe, Ru) were very slow even in the presence of [CpFe(CO)2]2 as a catalyst. However, when Me3NO.2H2O was added to the reaction mixture in solventless conditions, the non-salt product was obtained in a short period of time at 80oC. A range of cyclopentadienyl based metal complexes e.g [CpMo(CO)3]2, [MeCpRu(CO)2]2 etc. and palladium based compounds such as PdO, Pd/CaCO3 5% etc. were found to be good catalysts for the solventless reactions between CpFe(CO)2I and PPh3. Solventless migratory-insertion reactions have been successfully conducted between CpFe(CO)2CH3 and a range of solid phosphine ligands. Only the acetyl products, CpFe(CO)[PR3]COCH3 were obtained. SO2 insertion into RCpFe(CO)2R’ (R = H, CH3; R’ = CH3, CH2Ph) occurred quite easily at room temperature. However, when R was a carboxylic acid group, CO2H, no reaction took place. CO insertion into the same systems did not happen in solventless conditions.
