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

Palladium can tailor fullerenes: Palladium catalysts enable a number of CH bond transformations of organo(hydro)fullerene. In addition to anticipated coupling reactions (CH bond allylation and arylation), an unexpected new CH bond dimerization reaction and CC bond‐cleavage reaction were also uncovered.
