%X The reaction of [Rh(CO)2Cl]2 with CF3C&#8801;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&#8801;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 &#963;-cyclopentadienylthallium and with triphenylphosphine are (&#951;- C5H5)2Rh2(CO)2(CF3C2CF3)and Rh(CO)Cl(PPh3)2 respectively.
