New organometallic complexes of buckminsterfullerene having π-bondend nickel, palladium, or platinum with triorganophosphite ligands, and their characterisation
摘要:
We have prepared a series of novel pi-complexes of fullerene C-60 of the types [C-60{M(P(OR)(3))(2)}(n)], (M = Ni, Pd, or Pt; R = Ph, Bu, or Et; n = 1 or 2). The compounds have been characterised by mass spectrometry, electronic spectroscopy and proton, carbon, and phosphorus NMR spectroscopy. The sensitivity of these compounds to air increases greatly in the series Pt < Pd << Ni. Unlike analogous phosphine derivatives, the phosphite species do not readily form complexes with more than two metal atoms attached to the fullerene cage. In contrast with many pi-bonded fullerene derivatives, most of the compounds show molecular ions in the FAB mass spectrum.
