The chemical reactivity of fullerene C60 towards fac-Mo(CO)3 (MeCN)(dppe) and Mo(CO)4(dppe). Synthesis, characterization and reactions of the novel fullerene molybdenum derivative fac-Mo(CO)3(dppe)(η2-C60)
摘要:
The acetonitrile ligand of fac-Mo(CO)(3)(MeCN)(dppe)[dppe = bis-(1,2-diphenylphosphino)ethane] can be easily replaced by fullerene C-60 in chlorobenzene at about 80 degrees C to give exclusively fac-Mo(CO)(3)(dppe>(eta(2)-C-60), whereas fullerene C-60 reacted with Mo(CO)(4)(dppe) in refluxing chlorobenzene to afford an isomeric mixture of fac- and mer-Mo(CO)(3)(dppe)(eta(2)-C-60). These organomolybdenum C-60 derivatives were characterized by elemental analysis and spectroscopic techniques. In addition, the eta(2)-C-60 ligand in fac-Mo(CO)(3)(dppe)(eta(2)-C-60) was also found to be easily displaced by MeCN, PPh3 or pyridine to give corresponding fac-organomolybdenum complexes.
