This thesis is devoted to the study of oxygen reduction reaction catalysed by porphyrins at the interface between two immiscible electrolyte solutions (ITIES). Electrochemical and spectrophotometric techniques are introduced to these interfaces in order to ...
The knowledge and understanding of the mechanism as well as the rate constant of the solvent exchange reactions are fundamental, since these reactions represent an important step in complex formation reactions on metal ions. Solvent exchange reactions in a ...
Following several tragic chemical accidents that have occurred in recent years, some directives concerning chemical process safety have been issued. The Seveso directive, for example, requires a precise description of the consequences of a possible chemica ...
Electronic and vibrational spectra of benzo-15-crown-5 (B15C5) and benzo-18-crown-6 (B18C6) complexes with alkali metal ions, M+•B15C5 and M+•B18C6 (M = Li, Na, K, Rb and Cs), are measured using UV photodissociation (UVPD) and IR-UV double resonance spectr ...
Metal ions are essential elements in all living systems. Their detections and identifications in biological processes require different methodologies. Mass spectrometry is one of the commonly used techniques in bioinorganic analyses to fulfill these requir ...
The decomposition reaction of a water-soluble complex (see scheme; 1) in H2O confirms the existence of a unique bidentate pyridinol cofactor in [Fe]-hydrogenase. This unique moiety is confirmed for the first time by the decomposition of a well-defined mode ...
The oxygen reduction reaction by decamethylferrocene (DMFc), triggered by hydrophilic metallic cations behaving as Lewis acids towards water molecules in a homogeneous organic phase reaction, was investigated using cyclic voltammetry at the water|1,2-dichl ...
A modular approach for the synthesis of cage structures is described. Reactions of [(arene)RuCl2]2 [arene = p-cymene, 1,3,5-C6H3Me3, 1,3,5-C6H3(i-Pr)3] with formyl-substituted 3-hydroxy-2-pyridone ligands provide trinuclear metallamacrocycles with pendant ...
The Diels-Alder reaction has been examd. in room temp. ionic liqs. with high molar concns. of Lewis acids under various conditions. A molar ratio of 10% catalyst gave a large increase in the selectivity and the yield of the reaction. The effect of catalyst ...
Relatively little is known about the dynamics of electron-transfer reactions at low collision energy. We present a study of Penning ionization of ground-state methyl fluoride molecules by electronically excited neon atoms in the 13 μeV–4.8 meV (150 mK–56 K ...
