摘要

The addition of the ·But (R1) and ·P(O)(OPri)₂ (R2) radicals to pyrrolidino[60]fullerenes C₆₀CH₂NMeCHX (X = C₆H₄N(CH₂CH₂Cl)₂, 2,6-(But)₂C₆H₂OH, PhC₆H₄, and indol-3-yl) was studied by ESR spectroscopy. The rate constants of R1 radical addition to these compounds and dimerization of spin-adducts of the R1 radicals with pyrrolidino[60]fullerenes were determined. Pyrrolidino[60]fullerenes manifest considerably higher reactivity toward the R1 radicals than fullerene C₆₀ and methanofullerenes C₆₀CX1X2 (X1 = X2 = CO₂Et; X1 = CO₂Me, X2 = OP(OMe)₂, X1 = X2 = OP(OEt)₂).
