Corannulene (C20H10), a bowl shaped fullerene fragment have been a great interest recently due to the improvement of synthesis of corannulene. A variety of metal derivatives of corannulenes have been prepared1, all of these cases contained the metal coordinated to the surface through the π- bonding. However, corannulene derivatives with a transition metal complexed in a σ- fashion are rare. Here, we report the first complexes with transition metals directly bonded to the edge of corannulene derivatives. Reaction of halogen substituted corannulene with ML2 (M = Ni, Pt) (L = PEt3) results in oxidative addition products of nickel and platinum corannulene derivatives characterized by NMR and X-ray crystallography.
