Abstract
The
reaction of [Rh(CO)2Cl]2 with
CF3C≡CCF3 gives a fluorocarbon-rhodium complex of
approximate formula [RhCl(CO)2 or 3(C4F6)]n,xH2O,yC6H6.
The complex is an intermediate in the formation of tetrakis(trifluoromethyl)cyclopentadienone from CF3C≡CCF3
and CO in the presence of[Rh(CO)2Cl]2.
The molecular structure of the complex remains obscure despite extensive study
of its spectroscopic and chemical properties. The major products formed in the
reactions of the complex with σ-cyclopentadienylthallium and with
triphenylphosphine are (η- C5H5)2Rh2(CO)2(CF3C2CF3)and
Rh(CO)Cl(PPh3)2
respectively.
