Abstract
The ESR spectra of the radicals resulting from the multiple addition of diisopropoxyphosphoryl radicals to C60 have been studied. The formation of six different types of radical adducts was detected. A structure for the stable product, characterized by hyperfine coupling of the unpaired electron with two phosphorus nuclei, was proposed. The unpaired electron in C60P(O)(OPri)2 is delocalized in the same way as in alkylfullerenyl radicals,i.e., mainly over the two six-membered rings adjacent to the C-CP(O)(OPri)2 bond.
