摘要:
Photolysis of cis-(CF3)(2)CF-Hg-Pt(PPh3),-CH=CPh2 in a saturated toluene solution of C-60 has generated the platinum-centered free radical, which adds to C-60 to give a spin-adduct cis-Ph2C=CH-Pt(PPh3)(2)-C-60(.) fully characterized by EPR spectroscopy. Phosphorylfullerenyl radicals containing a eta(2)-coordinated ML2 moiety have been prepared, starting from phosphorylfullerenyl radical dimers. The metal complex (eta(2)-C-70)Pd[(+)DIOP] has been shown to undergo the partial rupture of M-C bonding as a consequence of the phosphoryl radical attack on the metal atom to give three regioisomers of metal-containing fullerenyl radicals.
