The reaction of [Rhκ2-O2S(O)CF3}(PiPr3)2] (1) with ethynylferrocene in the presence of KF affords the substituted vinylidene complex trans-[RhFCCH(C5H4)Fe(C5H5)}(PiPr3)2] (2) which upon treatment with the butadiyne derivative Ph3SnCCCCSnPh3 produces the chain-like compound trans-[(μ-CCCC)Rh(CCH(C5H4)Fe(C5H5))(PiPr3)2}2] (7). The triflato complex 1 reacts with 1,4-C6H4(CCH)2 to give the
