    [Ru(CO)2(PPh3)3] reacts with either HC=CCH2Br or [HC=CCH2SMe2]Br to provide the σ-allenyl complex [Ru(CH=C=CH2)Br(CO)2(PPh 3)2]; however, with [HC=CCH2PPh3]Br, the salt [Ru(γ2-H2C=C=CHPPh3)(CO) 2(PPh3)2]Br is obtained, which may be described as a complex of a phosphonioallene on the basis of crystallographic data for [Ru(γ2-H2C=C=CHPPh3)(CO) 2(PPh3)2]2Br(PF6) and a comparison of spectroscopic data with those for the simple allene complex [Ru(γ2-H2C=C=CH2)(CO) 2(PPh3)2].
