The oxidation of hydrocarbons under soft and selective conditions is a reaction almost exclusively produced under these conditions by enzymes. A lot of these enzymes, posses iron in their metal center, ...
Haraburda, Ewelina (Fecha de defensa: 2015-07-28)
The development of new chemical processes for the formation of carbon-carbon bonds is an important topic in organic chemistry. In particular, the transition metal catalysed [2+2+2] cycloaddition reaction ...

Se han sintetizado dos nuevos complejos mononucleares de Ru, con formula [RuCl2(Hbpp)(dmso)2], a partir de la reacción entre [RuCl2(dmso)4] y Hbpp (3,5-bis(2-piridil)pirazola). El hecho que sólo tres ...
Feixas Geronès, Ferran (Fecha de defensa: 2011-02-04)
Interactions between electrons determine the structure and properties of matter from molecules to solids. Therefore, the understanding of the electronic structure of molecules will enable us to extract ...
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 ...
Corona Prieto, Teresa (Fecha de defensa: 2017-02-17)
The transformation of C-H bonds into C-O/N bonds is a process of interest in organic synthesis, but controlling the reactivity and selectivity among the multiple C-H bonds existing in most molecules is ...
Dantignana, Valeria (Fecha 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 ...
Parera Briansó, Magda (Fecha de defensa: 2014-05-20)
The transition-metal catalysed [2+2+2] cycloaddition reaction is a highly efficient synthetic tool that allows six-membered polysubstituted carbo- and heterocyclic derivatives to be obtained in an atom ...
Rodríguez Serrat, Mònica (Fecha de defensa: 2019-09-27)
In the last decades, carbenes have shown a huge potential and versatility in organometallic and organic chemistry. In each of these fields, first row transition metal chemistry is less developed than ...
Ben Amar, Marwa (Fecha de defensa: 2021-10-22)
Wastewater discharged from industrial and agricultural activities contains relatively large amounts of toxic metal ions, especially including Cd(II), Cu(II), Pb (II), and Cr(VI). The removal of these ...
