Abstract
Dibenzo[g,p]chrysenes were readily synthesized via the superacid- or TiF4-mediated domino Friedel-Crafts-type cyclization of 1,1-difluoroethenes bearing two biaryl groups, which were easily prepared via the Suzuki-Miyaura coupling of 1,1-difluoro-2,2-diiodoethene or 1-(biphenyl-2-yl)-1-bromo-2,2-difluoroethene. Using this approach, the activation of both vinylic and aromatic C-F bonds was successfully achieved to make new C-C bonds.
