, expanding its π-skeleton through the Barton–Kellogg and Scholl reactions led to the successful synthesis of a curved polycyclic arene containing three heptagons and two pentagons.

characterization of 6 was achieved by X-ray analysis using a single crystal of 6a (Figure 2), and it was found that the iodoarylation products 6 have a seven-memberedcarbocycle bearing adjacent difluoromethylene and iodomethylene units.
In addition, a selective HI elimination from 6a could be achieved by the
