Complessi di argento e rame con leganti carbenici N-eterociclici-fenolato (NHC-O): sintesi, caratterizzazione e studi catalitici nella reazione di formilazione e metilazione riduttiva di ammine con CO2

The high atmospheric concentration of carbon dioxide is one of the global warming causes. One action that can be pursued to reduce its high concentration levels is the CO2 capture and use as a C1 building block in reactions. This work examined the CO2 chemical valorisation through the homogeneous catalysis of inexpensive and abundant metals. Indeed, a copper(II) complex with N-heteorcyclic carbene-phenolate ligands (NHC-O) was synthesized. Thus, it was studied on two reactions: the reductive formylation and methylation of amines with CO2 and the hydrosilylation of amides. Furthermore, a novel silver(I) complex with NHC-O ligands was synthesized and characterized. In addition, several synthesis attempts of iron(II) and copper(I) complexes with NHC ligands were performed through different synthetic routes.
