Asymmetric epoxidation is one of the most important reactions in synthetic organic chemistry, because chiral epoxides act as versatile electrophiles which can be converted in a number of interesting and ...
Casitas Montero, Alícia (Fecha de defensa: 2012-06-01)
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 ...
Gómez Martín, Laura (Fecha de defensa: 2010-06-04)
La gran eficiència, selectivitat i les condicions suaus exhibides per les reaccions que tenen lloc al centre actiu de les metal·looxigenases són la font d'inspiració per la present dissertació. Amb ...
Garcia Bosch, Isaac (Fecha de defensa: 2011-12-20)
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 ...
Canta i Roldós, Mercè (Fecha de defensa: 2014-07-29)
Catalytic oxidation reactions of hydrocarbons that occur in the active site of metalloenzymes exhibit high efficiency and exquisite regio- and stereoselectivity under mild experimental conditions. We ...
Prat Casellas, Irene (Fecha de defensa: 2013-06-14)
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 ...
García Simón, Cristina (Fecha de defensa: 2015-04-10)
Coordination-driven self-assembly has led to the realization of an increasing number of elegant and sophisticated functional structures, the structural complexity of which would be difficult to achieve ...
Font Molins, Marc (Fecha de defensa: 2015-02-13)
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 ...
Cianfanelli, Marco (Fecha de defensa: 2021-12-03)
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 ...
