Resumen:
The work described in this thesis shows studies towards new applications of Schiff base complexes in homogeneous catalysis . Specifically, we investigated “salen” ligands (including N2S2 chelating systems) and also examined other aspects that are generally considered important in the context of increasing the sustainability of chemical processes. Studies on the use of these Lewis acidic compounds in the catalysis of the fixation of carbon dioxide, multicomponent reactions for the synthesis of substituted indoles and the recycling of triptycene based supramolecular aggregates revealed a wide potential of application. The Zn(salen) compexeswere evaluated as 'spectators' in the construction of supramolecular ligands based on bulky phosphines which proved to be useful in hydrosilylation catalysis. Therefore, the work described in this thesis may serve as a starting point for the development of a new catalytic potential of Schiff base complexes.
