SYNTHESIS OF POLYDIPHENYLPHOSPHITE DERIVATIVES OF [60]FULLERENE AND THEIR REACTIONS WITH METAL-COMPLEXES

Fullerenol C-60(OH)(12) reacts with chlorodiphenylphosphine to yield a polydiphenylphosphite derivative, C-60(OPPh2)(12) (1), which easily o xidizes and hydrolyzes giving different products, two of them, of comp osition C-60(OPPh2)(6)(OH)(6) 6DPA . x(H2O) (s = 6, 12) (3a') and C-60 [OP(O)Ph-2](5)(OH)(7). 7DPA (3b) were fully characterized (DPA = diphe nylphosphinic acid). A FAB study of 3b was performed. Compounds C-60(O PPh2)(12-x)(OH)(x) (x = 0, 1; s = 6, 3a) act as polydiphenylphosphite ligands and can be protected from oxidation by complexation. Rh, Mo an d Ru complexes containing ligands 1 and or 3a have been isolated and c haracterized by analytical and spectroscopic methods. (C) 1997 Elsevie r Science S.A.
