Enzymes are high-weight molecules which catalyze most of the metabolic processes in living organisms. Very often, these proteins contain one or more 1st row transition metal ions in their active center ...
In this thesis we developed a protocol for the intramolecular oxidation of prochiral secondary C-H bonds in which carboxylic acids, acting as directing groups for the oxidant species, promoted a highly ...
Aryl-Cu(III) species have been often implicated as the intermediate species that operate Ullmann-type couplings. However, such species have long remained elusive and the fundamental pathways that govern ...
The development of supramolecular assemblies with big cavities is important to recognize specific guests or infer a chemo- or regioselective chemistry, in analogy to natural enzymes. The objective of ...
The functionalization of hydrocarbons in a sustainable manner is one of the main challenges for chemists. Their abundance in nature as natural gas or crude oil makes them the most convenient chemical ...
This Ph.D. dissertation describes the synthesis and characterization of bench-top stable aryl-Co(III) organometallic species using commercially available cobalt(II) salts and a macrocyclic model substrate. ...
The development of new methodologies for the construction of complex molecules is one of the principal objectives in synthetic organic chemistry. Although huge advances have been made on cross-coupling ...
This thesis is focused on the unexplored field of organometallic copper(III) chemistry. Arylcopper(III) complexes have been proposed as key intermediates in Ullmann condensation reactions that consist ...
During the last decades, computational chemistry has become a resourceful tool in the quest to understand and predict the mechanism and the reactivity of chemical systems. This is especially true in ...
Organometallic aryl-CuIII species have been proposed as key intermediates in Ullmann-type reactions. However, such species have long remained elusive and mechanistic investigations of a plausible catalytic ...
