L'activació d'oxigen que té lloc en els éssers vius constitueix una font d'inspiració pel desenvolupament d'alternatives als oxidants tradicionals, considerats altament tòxics i nocius. En aquesta treball ...

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 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 ...

Oxidations are an important kind of reactions which are traditionally performed using stoichiometric oxidants that generate a large amount of waste. Syn-dihydroxylation of alkenes is a paradigmatic ...
Milan, Michela (Data de defensa: 2018-10-30)
The oxidation of aliphatic C-H bonds is a very powerful reaction because it allows the functionalization of inert C-H bonds, converting them into a suitable sites for further chemical elaboration. It ...

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 ...
López Lastra, Adrián (Data de defensa: 2020-07-28)
Polymers are one of the most used compounds in the chemical industry because they have application in a wide variety of products for daily use. Polymer preparation and its analysis is a very active field ...
