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.
