Reactions of the dirhenium(II) complexes Re2X4(μ-dppm)2 (X = Cl, Br; dppm = Ph2PCH2PPh2) with isocyanides Part XX. Oxidation of the complexes Re2X4(μ-dppm)2(L) (X = Cl or Br; dppm = Ph2PCH2PPh2; L = t-BuNC, XylNC or CO)

The reactions of the halogens X2 (X = Cl or Br) with the diamagnetic dirhenium(II) complexes Re2X4(μ-dppm)2(L), where dppm = Ph2PCH2PPh2, X = Cl or Br, and L = XylNC (xylyl isocyanide), t-BuNC or CO, and with salts of the edge-sharing bioctahedral species [Re2X3(μ-dppm)2(CO)(NCMe)2] +, provide convenient routes to the dirhenium(III) species [Re2X5(μ-dppm)2(L)]+. These cations, where L = XylNC, t-BuNC or CO, have been isolated as their halide (Cl- or Br3-), [PF6]- and [O3SCF3]- salts. IR spectroscopy shows that terminal RNC and CO ligands are present, and a crystal structure determination of the complex [Re2Cl5(μ-dppm)2(CO)]PF6 confirms that the cation has the edge-sharing bioctahedral structure [Re2(μ-Cl)2(μ-dppm)2Cl 3(CO)]+ with a formal Re=Re bond (Re-Re distance = 2.6607(4) A?). 31P-NMR spectroscopy indicates that these salts are weakly paramagnetic, with their P resonances exhibiting unusually large upfield shifts.

Mixed carbonyl-nitrile complexes of dirhenium(II). the structural characterization and reactivity of salts of the [Re2Cl3(μ-dPPm)2(CO)(NCMe)n] + cations (dppm = Ph2PCH2PPh2, n = 1 or 2)

The monocarbonyl complexes Re2X4(μ-dppm)2(CO) (X = Cl or Br) react with stoichiometric quantities of the nitriles RCN (R = Me or Ph) in the presence of TlY (Y = PF6 or O3SCF3) to afford complexes of the type [Re2X3(μ-dppm)2(CO)(NCR)]Y and [Re2X3(μ-dppm)2(CO)(NCR)2]Y in high yield. Crystal structure determinations on the salts [Re2Cl3(μ-dppm)2(CO)(NCMe)]O 3SCF3 and [Re2Cl3(μ-dppm)2(CO)(NCMe) 2]ReO4 have shown that the former has the unsymmetrical structure [(MeCN)(CO)ClRe(μ-dppm)2ReCl2]+ with a Re≡Re bond (Re-Re distance 2.2881(7) A?), while the bis-nitrile complex is the edge-sharing bioctahedron [(MeCN)ClRe(μ-Cl)(μ-CO)(μ-dppm)2ReCl(NCMe)]+, with an all-cis arrangement of the μ-CO and two MeCN ligands and a Re=Re bond (Re-Re distance 2.5669(4) A?). The species [Re2X3(μ-dppm)2(CO)(NCMe)]+ and [Re2X3(μ-dppm)2(CO)(NCMe)2] + readily interconvert upon the addition or loss of an acetonitrile ligand and, along with their benzonitrile analogues, they react with halide, XylNC and acetylene to afford Re2X4(μ-dppm)2(CO), [Re2X3(μ-dppm)2(CO)(CNXyl)2]Y and [Re2X3(μ-dppm)2(CO)(η2-C 2H2)]Y, respectively.
