AlCl3-Catalyzed Tandem Acetylation of Hydroarylated [60]Fullerenes
摘要:
The AlCl(3)-catalyzed acetylation of 1,2-hydrophenylated [60]fullerenes, HC(60)-Ar, proceeded via a sequential manner involving the acetylation at the hydrogenated fullerene carbon, the following intramolecular cyclization with the adjacent aryl group, the facile loss of water, and the second acetylation of the generated indenylidene double bond. However, the similar reaction of the hydrobiphenylated analogue brought about the normal acetylation at the terminal aromatic ring prior to the same sequential reactions as did hydrophenylated fullerenes.

The mechanochemical reaction of fullerene C-60 with organic bromides and alkali metals was found to give the corresponding aryl or alkyl C-60 derivatives under the solvent-free conditions.
Selective Introduction of Organic Groups to C60 and C70 Using Organoboron Compounds and Rhodium Catalyst: A New Synthetic Approach to Organo(hydro)fullerenes
A Rh‐catalyzed reaction of C60 and C70 with organoboroncompounds is described. This new catalytic method enables introduction of various organicgroups onto C60 and C70. [Rh(cod)(MeCN)2]BF4 proved to be the most effective catalyst in terms of productivity and selectivity. The reaction generally proceeds with a high regioselectivity and in a mono‐addition selective manner. It was found that water is
