La presente Tesis Doctoral se ha concebido como una continuación natural de trabajos realizados por nuestro grupo de Investigación y pretende efectuar una nueva contribución a la química de los elementos de Mo y W en las dos áreas antes citadas. En el primer c ... apítulo se estudian diversos complejos de estos elementos con ligados de tipo...

Imido ligands have been widely used as stabilizing ligands in highoxidationstate transition metal complexes. Their chemistry has experienced a remarkable growth due to the role they play in many important reactions. Following our interest in this area, we have extended our recent results in the synthesis of bis(imido) complexes of molybdenum,...

The zinc thiodipropionate complex [Zn(tdp)] (1) [tdp = S(CH 2CH2COO)22-] was obtained by reaction of aqueous zinc dichloride with a 1:1 mixture of Na2CO 3 and thiodipropionic acid. The bonding preferences of the tdp anion were studied by DFT methods. The reaction of 1 with o-phenanthroline (phen) gave the dinuclear compound...

Compounds [Bu4N]2[V8O16(oda)4⊂2Cl], 1, [Bu4N]2[V8O16(glut)4⊂2Cl], 2, and [Bu4N][V4O8(glut)2⊂F], 3, (oda = oxydiacetate, O(CH2COO)2 2−; glut = glutarate, CH2(CH2COO)2 2−) were obtained by a stepwise reaction of in situ prepared [Bu4N]VO3 with HCl (or HF for 3) and then with the dicarboxylic acid X(CH2COOH)2 (X = O and CH2), under appropriate...

Biphasic catalytic olefin epoxidation systems consisting of oxodiperoxomolybdenum catalysts in 1- n -alkyl-3-methylimidazolium hexafluorophosphate ionic liquid (IL) media with aqueous hydrogen peroxide oxidant were optimised by tuning the molecular structure of the IL and employing N -heterocyclic donor base additives to inhibit hydrolysis and...

Compounds based on imidazole or imidazolium moieties are excellent building blocks for the preparation of a plethora of ligand precursors. The introduction of chirality in these compounds is relatively easy through the Debus-Radziszewski reaction, in which the chiral pools are natural or non-natural amino acids. Using this synthetic route,...
