Resum:
In the last years, there is an increasing interest in substituting old technologies by cleaner catalytic alternatives to afford more environmental friendly processes in the chemical industry. In this way, it is a continuous challenge to find new base catalysts able to perform, with high activity and selectivity, reactions for the synthesis of pharmaceutical and fine chemicals.The research described in this thesis has focused on the study of new synthesis protocols for base catalysts. New types of hydrotalcite-like materials with controlled basicity were obtained. Also, a new synthesis protocol for short aliphatic chain ionic liquids and an extensive study of their physico-chemical properties is presented. Their basic properties have been characterized by several techniques and by illustrative test reactions. The work done in this thesis can be regarded as a progress in the design of new catalytic systems, more active and efficient for use in fine chemical processes.
