Silylmethylations of C60 with Grignard Reagents: Selective Synthesis of HC60CH2SiMe2Y and C60(CH2SiMe2Y)2 with Selection of Solvents

The search for biologically active compounds requires the further research into fullerene derivatives and their potential utility in materials science. This paper concerns the addition of Grignard reagents unexpectedly provided two types of silicon-containing fullerene derivatives. Selective preparation of these derivatives is dependent on the appropriate solvent. 2 figs.
