Abstract
The ESR spectra of the radicals resulting from the multiple addition o f diisopropoxyphosphoryl radicals to C-60 have been studied. The forma tion of six different types of radical adducts was detected. A structu re for the stable product, characterized by hyperfine coupling of the unpaired electron with two phosphorus nuclei, was proposed. The unpair ed electron in C60P(O)(OPri)(2) is delocalized in the same way as in a lkylfullerenyl radicals, i.e., mainly over the two six-membered rings adjacent to the C-CP(O)(OPri)(2) bond.
