Capdevila Güell, Lorena (Data de defensa: 2022-07-22)
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 ...
Ubasart Clarà, Ernest (Data de defensa: 2022-10-28)
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 ...
Casitas Montero, Alícia (Data 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 ...
Serra Parareda, Jordi (Data de defensa: 2018-06-21)
Most of the different homogeneous reactions catalyzed by gold have been developed in the past fifteen years and stem from the ability of both Au(I) and Au(III) complexes to coordinate and activate ...
Magallón Gubau, Carla (Data de defensa: 2022-05-16)
Nowadays, one of the main goals in organic chemistry and fine industry is the development of new synthetic methodologies for the preparation of life-relevant products in a sustainable manner. The use ...
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 ...
Garcia Bosch, Isaac (Data 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 ...
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 ...
Rovira Coll, Mireia (Data de defensa: 2017-03-10)
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 ...
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 ...
