Rojo Solé, Josep Maria (Date of defense: 2022-11-02)
[eng] P-Stereogenic ligands have demonstrated to be highly efficient for asymmetric catalysis, especially in metal-catalyzed asymmetric hydrogenation reactions. Among them, those bearing bulky substituents at phosphorus ...
Mancinelli, Andrea (Date of defense: 2017-04-21)
The development of selective methods for the direct conversion of carbon−hydrogen bonds into carbon-heteroatom and carbon−carbon bonds remains a critical challenge in organic chemistry. An interesting approach to address ...
Escriche Tur, Luis (Date of defense: 2016-11-21)
The main objective of this work is the synthesis of manganese compounds and hybrid materials that may be relevant from a bioinorganic and magnetic point of view. The developed strategy comprises three main steps that form ...
Llorens Palomo, Lluís (Date of defense: 2019-10-28)
Cucurbiturils are known to present potential applications in molecular recognition, self- assembly, and nanotechnology. The discovery of ultra-high affinity CB–guest complexes with binding constant values similar than those ...
Lobo Ruiz, Ariadna (Date of defense: 2019-05-10)
Peptides and proteins are essential substances for living organisms, as they can be found in every cell and tissue and are involved in many biological and physiological processes. Given their intrinsic properties and their ...
