Abstract
Regioselectivity of the addition of phosphoryl radicals to the products of cycloaddition of substituted nitriloxides to fullerene C60 was studied by ESR spectroscopy. The effect of fluorine-containing alcohols on the magnetic resonance parameters of the isomers of spinadducts of phosphoryl radicals located at different distances from the five-membered heterocycle was studied. Complexation of the obtained isomeric spin-adducts with (CF3(3COH leads to a 3 to 5 G increase in the constant of hyperfine interaction with the phosphorus nucleus, which makes it possible to observe additional lines in the ESR spectrum.
