S. Ballenweg et al., UNUSUAL FUNCTIONALIZATION OF C-60 VIA HYDROZIRCONATION - REACTIVITY OF THE C-60-ZR-IV COMPLEX VS ALKYL ZR-IV COMPLEXES, Journal of the Chemical Society, Chemical Communications, (19), 1994, pp. 2269-2270
The reaction of the C-60 hydrozirconation adduct 1 with N-bromosuccini
mide and m-chloroperbenzoic acid leads to the formation of Diels-Alder
products with bromo- and hydroxy-cyclopentadiene, respectively.
