In this work, we report the synthesis of a PAH molecule, formation of which consists of an unusual C-C bond cleavage accompanied by a complex π-conjugated molecular scaffold rearrangement. We demonstrate that the complex chemical transformation is steered by concerted motion of individual Au0 gold atoms on a supporting Au(111) surface. This observation underpins the importance of single-atom catalysis mediated by adatoms in on-surface synthesis as well as catalytic activity of single Au0 atoms facilitating cleavage of covalent carbon bonds.
