Funzionalizzazione di molecole organiche effettuate in CO2 supercritica come mezzo di reazione

Sustainable development is now accepted by the society as a necessary target for achieving societal, economic and environmental objectives. Within this, chemistry has a key role to play in maintaining and improving our quality of life, the competitiveness of the chemical industry and the natural environment. Chemical transformations such as alcohols oxidation produce large amount of hazardous waste. Catalysis being finest upon stoichiometrical synthesis seems to be a solution for selectivity, energetic and environmental concern. Similarly, the elimination of carcinogenic and bioaccumulating chlorinated (or aromatic) solvents in which these conversions are generally carried out is also highly desirable since, despite their relatively low price, solvents have a considerable life-cycle impact and the broader total costs of these typical volatile organic compounds (VOCs) are nonetheless high and constantly increasing. New, atomefficient heterogeneously catalysed oxidation processes in alternative reaction media are thus intensively investigated in current academy's and industry's research focusing on the immobilization of aerobic metal catalysts and on supercritical carbon dioxide (sc-CO2) or ionic liquids as reaction solvents. Hence, my Ph.D. research has been spent on develop systems for aerobic alcohols oxidation catalysed by tetrapropylammonium perruthenate (TPAP) or nanostructured palladium.
