Abstract: Acid-catalyzed Friedel–Crafts-type cyclization of tetrapyrrolic BF2 complex 1 and α,α′-dibromotripyrrin 2 gave 5,10,23-trimesityl [28]heptaphyrin(1.1.0.0.1.0.0) BF2 complex 3BF2 as a stable and moderate antiaromatic macrocycle. Demetalation of 3BF2 with methanesulfonic acid followed by treatment with HCl… read more here.
