  Rhenium multihydride heterobimetallic complexes containing bridging and chelating diphosphine ligands

  摘要：

  Treatment of the rhenium pentahydride complex [ReH5(dppen-PP')(dppm-P)] (dppen = Ph(2)PCH= CHPPh(2), dppm = Ph(2)PCH(2)PPh(2)) with 0.5 mol equivalents of [Rh2Cl2(cod)(2)] (cod = cycloocta-1.5-diene) gave the fluxional bimetallic complex [(dppen-PP')H3Re(mu-H)(2)(mu-dppm) Rh(cod)]Cl 1a, which was characterised as the corresponding PF6 salt 1b. Analogous complexes (Ic and Id) were prepared from [Rh2Cl2(nbd)(2)] [nbd = norbornadiene (bicyclo[2.2.1]hepta-2,5-diene)]. The fluxionality of 1b and 1d was studied by P-31-{H-1} and H-1 NMR spectroscopies over a range of temperatures. Treatment of [ReH5(dppen-PP')(dppm-P)] with silver iodide gave a fluxional rhenium-silver bimetallic complex formulated as [(dppen-PP')H3Re(mu-H)(2)(mu-dppm)Agl] which was studied by variable-temperature NMR spectroscopy.

  New multihydride complexes of rhenium containing diphosphine ligands: low-temperature protonation of [ReH₇(Ph₂PCHCHPPh₂-PP′)]

  摘要：

  Treatment of oxochloro complexes of tge type (ReOCl3(L-L)] (L-L = diphosphine) with sodium tetrahydroborate gave complexes of the type [ReH7(L-L)]. Treatment of [ReH7(dppen-PP)] la [dppen = cis-1,2-bis(diphenylphosphino)ethylene = cis-Ph2PCH=CHPPh2] with triphenylphosphine gave a mixture of the pentahydride [ReH5(dppen-PP)(PPh3)] and the trihydride (ReH3(dppen-PP')(PPh3)2]. However, treatment of la with dppm [bis(diphenylphosphino)methane, Ph2PCH2PPh2] in refluxing toluene, followed by slow crystallisation, gave [ReH5(dppen-PP)(dppm-P)] which was isolated and characterised by variable-temperature NMR spectroscopy. Prolonged heating of la with dppm gave the trihydride [ReH3(dppen-PP)(dppm-PP)], the fluxionality of which was studied by NMR spectroscopy between +90 and -70-degrees-C. Protonation of la with HBF4.Et2O, at -80-degrees-C, gave a complex formulated as [ReH6(eta2-H-2)(dppen-PP)]+ which, on warming to ambient temperature, was cleanly converted to a dirhenium multihydride species tentatively formulated as [(dppen-PP')H3Re(mu-H)2-ReH3(dppen-PP')] on the basis of IR and NMR evidence.
