The organometallic chemistry of C60 has attracted much attention concerning the effect of metal coordination on the properties of C60 since the discovery and macroscopic synthesis of C60. In our study, we try to synthesize two analogous ligands which contain two phosphines. And reaction of the new ligands and metal carbonyl clusters will produce new-type of metal complexes.
Addition of Ph2(Li)PBH3, prepared by n-BuLi-deprotonation of Ph2(H)PBH3 in THF, to toluene solution of C60 took place to give the adduct C60H2(Ph2PBH3)2 (2) after quenching with HCl in ethyl acetate. Reaction of C60 and sodium 1-propanethiolate in acetonitrile produces C602-, and then adding PPh2Cl to C602- solution to afford C60(PPh2)2 (8). Treatment of the borane complex 2 with diazabicyclo[2.2.2]octane (DABCO) in toluene removes the borane group to give the phosphine C60H2(PPh2)2 (3). Reaction of 3 and Os3(CO)10(NCMe)2 at room temperature produces Os3(CO)10(£g,£b3-(PPh2)C60H) (5) and C60H2(PPh2)2(Os3(CO)10)2 (6). Furthermore, reaction of 3 and Ru3(CO)12 at 85 ¢J produces Ru3(CO)10(£g,£b3-(PPh2)C60H) (7). The resulting compounds are characterized by NMR, IR, Mass, X-ray and EA.
