Antiaromatic polycyclic conjugated hydrocarbons (PCHs) are attractive research targets because of their interesting structural, electronic and magnetic properties. Unlike aromatic compounds, the synthesis of antiaromatic PCHs is challenging because of their high reactivity and lack of stability, which stems from the small energy gap between their highest occupied and lowest unoccupied molecular orbitals. Here we describe a strategy for the introduction of antiaromatic units in PCHs via thermally selective intra- and intermolecular ring-rearrangement reactions of dibromomethylene-functionalized molecular precursors upon sublimation on a hot Au(111) metal surface, not available in solution chemistry.
