Resum:
This thesis describes the development of new ligands with unusual properties to be applied in homogeneous catalysis. Three strategies were envisaged to obtain the the new ligand systems. Accordingly, the thesis is divided in three parts.<br/>The first part describes the design of phosphine ligands that include in their structure the azobenzene moiety, which occurs in two structurally different isomers. The effect of the isomerization on several catalytic reactions was studied.<br/>The second part presents the use of supramolecular interactions to induce chirality in a prochiral biaryl diphosphine. The formation of the supramolecular complexes and the effect on asymmetric catalysis were also investigated.
