Abstract:
The solution coordination chemistry of iron complexes with the pentadentate bispidine ligands L1, L2, and L3 (dimethyl 9-oxo-2,4-di(pyridin-2-yl)-3,7-diazabicyclo[3.3.1]nonane-1,5-dicarboxylate derivatives) was examined. While in acetonitrile, (L1,2)FeII/III species have a preference for Cl– as co-ligand. The corresponding aqua and hydroxido complexes also prevail in the presence of Cl– in aqueous solution. The observed FeII/III potentials in water (cyclic voltammetry) and potentials of (L1–3)FeIV=O (buffered and unbuffered aqueous solutions) are strikingly similar, i.e. the latter are assigne

Abstract:
In this work we have prepared octahedral non - heme iron species in high oxidation states. Iron (IV) - oxo and iron (IV) - imido complexes based on triazacyclononane scaffold had been synthesised and all of them had been spectroscopicaly characterised. We studied the reactivity of the oxo complexes in the oxygen atom transfer to sulfur atoms and in the abstraction of hydrogen from alkylbenzene substrates; in the case of imido complexes the transfer of imido group to sulfur atoms was studied. Moreover we studied the photolysis of iron - azide octahedral complexes to obtain high - valent iron -

The research described in this thesis concerns the synthesis and characterisation of manganese(II), iron(II), cobalt(II) and zinc(II) complexes bearing linear pentadentate ligands with N-, O- and S-donors. The complexes can be described by the general formula [LM(II)X2], where X is an anionic ligand such as chloride, bromide, triflate or hexafluoroantimonate, L is a linear pentadentate ligand and M is the metal(II) ion. Two aspects have been the main focus in this study: the coordination geometry of these complexes and their catalytic performance in the oxidation of hydrocarbons. The X-ray str

Abstract:
In this chapter, we describe a strategy for efficient and selective catalytic oxidation of organic substrates such as methane and aromatics in aqueous media. In this strategy, pentadentate ligands containing one N-heterocyclic carbene (NHC) moiety were employed as ancillary ligands of triplet FeIV–oxo complexes. The FeIV–oxo species show strong oxidation activity owing to the strong trans-influence of the NHC moiety. Upon introducing bulky aromatic substituents to the NHC ligand, the hydrophobic second coordination sphere (SCS) was successfully formed to surround the FeIV–oxo moiety and achiev
