Replacement of a chloride ion of cis- (PR3 = tertiary phosphine) by a cyclopentadienyl group from Tl(C5H5) or Hg(C5H5)2 results exclusively in the isomers of with C5H5 trans to PR3.The second chloride can be replaced when excess Tl(C5H5) is used.The ?-bonded cyclopentadienyl groups of either mono- or di-substituted compounds can readily exchange in solution with a chloride of cis- again producing exclusively the same isomers of .The cyclopentadienyl groups do not transfer as fast as chloride ions between the same species, but do so considerably faster than any accompanying CO scrambling processes.Cyclopentadienyl groups from the ?-bonded complexes, and from 5-C5H5)(PR3)2>Cl, can also be readily transferred to mercury when treated with HgCl2.
