(Date of defense: 16-07-2015)In this thesis we present the synthesis and characterization of different types of ruthenium complexes containing N-donor ligands together with dmso, Cl and H2O ligands, along with their complete characterization through ...
-
(Date of defense: 22-11-2013)In this thesis is presented the synthesis and characterization of two different carboranylcarboxylate ligands, 1-CH3-2-CO2H-1,2-closo-C2B10H10 and 1-CO2H-1,2-closo-C2B10H11, in which the methyl group bonded to the carbon ...

(Date of defense: 24-02-2012)The development of new chemical processes and efficient catalysts for the formation of carbon-carbon bonds is an important topic in organic chemistry. In particular, the [2+2+2] cycloaddition reaction involving different ...
-
(Date of defense: 08-06-2012)The catalytic asymmetric oxidation of alkenes has special interest from both industrial and academic points of view. For this reason, catalysts able to perform these reactions in a faster and more effective manner have ...
-
(Date of defense: 29-07-2014)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 describe the efficient ...
-
(Date of defense: 23-02-2018)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. Special attention ...
-
(Date of defense: 13-02-2015)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 Ullmann-type ...
