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. ...
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 ...
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 ...
In this thesis we present the synthesis and characterization of different types of ruthenium complexes containing N-donor ligands together with monodentate ligands, along with their complete ...
Aquesta Tesi Doctoral està dividida en diferents capítols tots ells basats en aplicacions de macrocicles nitrogenats triolefínics de 15 membres i dels seus complexos amb metalls de transició. En primer ...
ENG- Enzymes are natural catalysts that speed up biochemical reactions efficiently, but their use in industry is often limited because they are usually specific to certain substances and reactions. ...
La Tesi descriu de manera completa una sèrie de complexos de ruteni amb lligands polipiridílics i lligands auxiliars de tipus fosfina, dmso, nitril o aquo. Es descriuen estudis d'isomerització (cis/trans ...
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 ...
The oxidative activation of C(sp3)–H bonds under ambient conditions represents a challenge to modern chemistry, nevertheless it is commonly operated in Nature by various oxygenases in key metabolic ...
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 ...
