Substituents effects on the addition of silyllithium and germyllithium to C60

Mono-adducts 2 and di-adducts 3 are obtained by the reaction with silyllithium and germyllithium 1 with C60. The selectivities of the products are controlled by electronic and steric effects of the substituents. Formations of 1,4-adduct 4 and dimer 5 can be obtained in the presence of biphenyl derivatives.

Photochemical functionalizations of C60 with phenylpolysilanes

Photolyses of tert-butyl substituted disilanes 1a-1c, and 1i with C60 result in the formation of 1,16-adduct 2 through silyl radical addition to fullerene. The unusual products, 3, 5, 6 and 7 where the silyl and phenyl groups attached on 1,2-positions of fullerene are also obtained from the reaction of 1d-g and 4. The structures of all these compounds were determined by one- and two-dimensional NMR techniques.
