N2 - Stoichiometric amounts of RuCl(PPh3)2(η-C5H5) and dppm react in refluxing C6H6 to give RuCl-(PPh3)(η1-dppm)(η-C5H5), which has been fully characterized by an X-ray study (triclinic, space group P 1, a 22 377(6), b 9 913(2), c 9 826(3)Å, α 70 46(2), β 78 72(2), γ 80 40(2)°, Z 2) in which 3299 data [I > 3σ(I)] were refined to R 0 046, R’ 0 052. Structural parameters are similar to those of other RuX(PR3)2(η-C5H5) complexes. The chloro complex was converted into [Ru(PPh3)(η2-dppm)(η-C5H5)]+ salts; the other PPh3 ligand can be replaced by a second dppm ligand to give [Ru(dppm)2(η-C5H5)]+, which contains both mono- and bidentate dppm ligands. Alkylation of the uncoordinated phosphorus with Mel is accompanied by halogen exchange to give [RuI(PPh3)-(PPh2CH2PMePh2)(η-C5H5)] I, while reactions with a variety of transition metal complexes result in abstraction of PPh3and formation of RuCl(dppm)(η-C5H5).
