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 ...
Soler Vives, Marta (Data de defensa: 2015-02-02)
Nowadays, the search for new drugs against cancer is one of the major goals to improve the quality of life of patients. The development of more selective treatments against cancer cells may lead to a ...
Dantignana, Valeria (Data de defensa: 2020-12-03)
Selective oxidation of C-H bonds is an important reaction, as it can disclose novel synthetic strategies to get functionalized products through efficient paths. Nonetheless, due to the inert character ...
Gómez Martín, Laura (Data 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 ...
Call Quintana, Arnau (Data de defensa: 2016-12-13)
The increasing need for more efficient synthetic methods and sustainable processes for fuel and high-value organic molecules production can be seen as one of the major challenging goals for the future. ...
Prat Casellas, Irene (Data 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 ...
Company Casadevall, Anna (Data de defensa: 2008-12-16)
L'activació d'oxigen que té lloc en els éssers vius constitueix una font d'inspiració pel desenvolupament d'alternatives als oxidants tradicionals, considerats altament tòxics i nocius. En aquesta treball ...
Font Molins, Marc (Data 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 (Data 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 ...
Borrell Recasens, Margarida (Data de defensa: 2021-11-05)
Oxidations are an important kind of reactions which are traditionally performed using stoichiometric oxidants that generate a large amount of waste. Syn-dihydroxylation of alkenes is a paradigmatic ...
