La gran eficiència, selectivitat i les condicions suaus exhibides per les reaccions que tenen lloc al centre actiu de les metal·looxigenases són la font d'inspiració per la present dissertació. Amb ...
Call Quintana, Arnau (Fecha de defensa: 2016-12-13)
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. ...
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 ...

This Ph.D. dissertation describes the synthesis and characterization of bench-top stable aryl-Co(III) organometallic species using commercially available cobalt(II) salts and a macrocyclic model substrate. ...
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 ...
