RESUMO

The reactivity of fullerene-60 was explored on the formation of platinum-fullerene complexes using a variety of ligands, such as: triphenylphosphine, tricyclohexylprosphine, trimetylphosphite, tri-n-butylphosphine, trimethylphosphine, tert-butylisocyanide and carbonyl. The products were obtained from reactions between fullerene [60] and zerovalent platinum compounds at ambient temperature and inert atmosphere, using the Schlenk technique. All solvents used were previously purified and distilled at this atmosphere. The following complexes were obtained: [Pt(PCy3)(C60)], [Pt(C2H4)(PPh3)(C60)], [Pt{P(OMe)3}2(C60)], [Pt{P(n-Bu)3}2(C60)], [Pt(PCy3)(PPh3)(C60)], [Pt(PPh3)2(C60)], [Pt(PCy3){P(OMe)3}(C60)], [Pt(PCy3)(CNBut)(C60)], [Pt(PCy3)(CO)(C60)], [Pt(PCy3)(PMe3)(C60)], [Pt(PMe3)2(C60)], [Pt(PPh3)(PMe3)(C60)]. All products were spectrocopically characterized by infrared, Raman, NMR H e P and elementary analysis.
