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 ...
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 ...
Serra Parareda, Jordi (Fecha 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 (Fecha 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 ...
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 ...

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 ...
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 ...
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 ...
