S. Ballenweg et al., HYDROGENATION OF BUCKMINSTERFULLERENE C-60 VIA HYDROZIRCONATION - A NEW WAY TO ORGANOFULLERENES, Tetrahedron letters, 34(23), 1993, pp. 3737-3740
Hydrogenation of buckminsterfullerene C60 has been achieved via reacti
on with (eta5-C5H5)2Zr(H)Cl (hydrozirconation). Hydrolysis of the inte
rmediate C60 zirconium(IV) complex, [(eta5-C5H5)2ZrCl]nC60Hn with n=1,
2,3 yielded a mixture of C60H2n and unreacted C60, from which C60H2 ha
s been isolated through preparative high performance liquid chromatogr
aphy (HPLC).
