W. Bidell et al., A DIELS-ALDER ADDUCT OF C-60 CONTAINING HYDROXYQUINONE FUNCTIONALITIES, Journal of the Chemical Society, Chemical Communications, (14), 1994, pp. 1641-1642
Two new Diels-Alder adducts of C-60 have been prepared from 1,3-diphen
ylisobenzofuran and the ortho-quinodimethane generated from 1,4-dihydr
oxy-2,3-bis(bromomethyl)anthraquinone: the dihydroxy anthraquinone-C-6
0 adduct readily undergoes deprotonation to give the corresponding dia
nion.
