En aquesta tesi s'han sintetitzat macrocicles nitrogenats poliinsaturats de diferents mides i s'ha estudiat la seva reactivitat. <br/>S'han preparat macrocicles de quinze i setze baules triacetilènics i de quinze baules ...
Duran i Carpintero, Josep (Date of defense: 1999-07-22)
The oxidative addition proved to be a useful method to prepare platinum (II) hydridotiolate by reaction of tetrakis(triphenylphosphine)platinum(0) with aminothiolate and phosphinothiolate ligands like cysteamine, cysteine ...
Moradell Rabert, Sílvia (Date of defense: 2002-12-13)
El cisplatí, PtCl2(NH3)2, ha estat una de les drogues més utilitzades en la quimioteràpia del càncer des del descobriment de la seva activitat. Però degut a la seva alta toxicitat i greus efectes secundaris, s'han sintetitzat ...
Xifra Garcia, Raül (Date of defense: 2005-01-28)
· S'ha preparat i caracteritzat una família de complexos de Cu(III) contenint lligands triazamacrocíclics, estudiant-se les seves propietats estructurals, espectroscòpiques i redox. Aquesta àmplia família de complexos tenen ...
Sánchez Navarro, Juan Manuel (Date of defense: 1999-03-17)
For the selective separation of Noble Metals, different new chelating polymers with the same functional group, based on tri-isobutylphosphine sulphide, have been synthesised. Different spacers between the polymeric matrix ...
Borrell Recasens, Margarida (Date of defense: 2021-11-05)
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 example because it is ...
Ng Choi, I-teng Montserrat (Date of defense: 2015-12-15)
The incorporation of unsymmetrical biaryl systems into peptide sequences is a strategy that can improve their biological activity. Due to the difficulty of arylating the 4(5}-position of the imidazole ring, this doctoral ...
Rosés Subirós, Cristina (Date of defense: 2016-01-22)
