synthetic method for the preparation of polycyclic aromatic hydrocarbons, polycyclic heteroaromatic compounds, and nanographenes. Among the many examples, anionic cyclodehydrogenation using potassium(0) has attracted synthetic chemists because of its irreplaceable reactivity and utility in obtaining rylene structures from binaphthyl derivatives. However, existing methods are difficult to use in terms of practicality
Towards nanographenes: Domino-DPEX (dehydrative π-extension) is a new synthetic approach to extended nanographenes containing a perylene or terrylene core. The pronounced regioselctivity towards aldehyde groups in different positions makes DPEX an excellent tool for implementing pre-programmed multiple annulation of simple precursors of elusive nanographenes. This approach enables the formation of
