Ja. Chen et al., ISOMERICALLY PURE ORGANO[60]FULLERENES FROM C-60(2-) SALT - SYNTHESISAND CHARACTERIZATION OF 1-BENZYL-2-HYDRO[60]FULLERENE, Journal of the Chemical Society, Chemical Communications, (15), 1995, pp. 1553-1554
Isomerically pure 1-benzyl-2-hydro[60]fullerene is synthesized in 64%
yield by the reaction of C-60(2-) potassium salt with benzyl chloride
in THF at 50 degrees C.
