Popis: | Addition of the ·P(O)(OPri)2, Me·, Et·, ·But, and Cl3C· radicals to the (ν2-C60)Os(CO)-(PPh3)2(CNBut) complex (1) was studied by ESR spectroscopy. The spectral parameters of the spin-adducts of these radicals with complex 1 were determined. The predominant direction of the attack by the ·P(O)(OPri)2, ·But, and Cl3C· radicals are the cis-1 and cis-2 bonds of the fullerene molecule. The stability of the spin-adducts depends substantially on the nature of the added radical. The addition rate constants of the ·P(O)(OPri)2, ·But, and Cl3C· radicals to complex 1 and the dimerization rate constants for these spin-adducts were determined. |
