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 of C-H bonds, the use ...
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 site-selective and ...
Roldán Gómez, Steven (Fecha de defensa: 2020-01-14)
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 the area of ...
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 describe the efficient ...
Call Quintana, Arnau (Fecha 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. Nature has developed ...
Font Rubio, Pau (Fecha de defensa: 2023-10-06)
Homogeneous reactions catalyzed by gold have mainly been developed in the past two decades, stemming from the proneness of Au(I) and Au(III) complexes to coordinate and activate carbon-carbon multiple bonds towards a ...

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 useful chiral ...
Vicens Serra, Laia (Fecha de defensa: 2023-07-18)
Most of the organic molecules used in chemical industry (and their synthetic precursors) contain oxygen atoms in their structure. One of the most convenient methods for the preparation of oxygenated compounds is the ...
Codolà Duch, Zoel (Fecha de defensa: 2014-07-11)
Harness light from the sun is one of the 21st century’s major goals towards the substitution of fossil fuels for a renewable source of energy. Sustainable production of highly energetic molecules using sunlight as energy ...
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 Ullmann-type ...
Ubasart Clarà, Ernest (Fecha 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 this thesis was to ...
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 using conventional ...
