Resumen de Polycyclic Aromatic Hydrocarbons (PAHs) containing Biphenylene and Cyclooctatetraene Units
Polycyclic aromatic hydrocarbons (PAHs) are a family of organic compounds presents around us from oil to interstellar space, that can be considered as well-defined graphene fragments. Defective PAHs with non hexagonal rings have emerge as improved scaffolds due to their ability to modify the properties of their planar analogous. The synthesis of both systems generally requires regioselective rings fusions, where metal-catalysed annulations have become one of the most attractive strategies. Throughout this PhD thesis, 1,3- cyclohexadiene nuclei, presents in dihydrobiphenylenes systems, will be explored towards annulated systems containing biphenylenes units through oxidative process. Moreover, synthesis and reactivity of strained alkynes species (COTynes) for the formation of PAHs with COT units will also be adressed.
