  Cyclic Trinuclear Rh₂M Complexes (M = Rh, Pt, Pd, Ni) Supported by meso-1,3-Bis[(diphenylphosphinomethyl)phenylphosphino]propane

  摘要：

  Reaction of [MCl2(cod)] (M = Pd, Pt) with a tetraphosphine, meso-1,3-bis[(diphenylphosphinomethyl)phenylphosphino]propane (dpmppp), afforded the mononuclear complexes [MCl2(dpmppp)] (M = Pd (3a), Pt (3b)), in which the dpmppp ligand coordinated to the M ion by two inner phosphorus atoms to form a six-membered chelate ring with two outer phosphines uncoordinated. The pendant outer phosphines readily reacted with [RhCl(CO)(2)](2) to give the cationic heterotrinuclear complexes [MRh2(mu-Cl)(3)(mu-dpmppp) (CO)(2)]X (X = [RhCl(CO)(2)](2), M = Pd (4a), Pt (4b); X = PF6, M = Pd (5a), Pt (5b)). The nickel analogue [NiRh2(mu-Cl)(3)(mu-dpmppp)(CO)(2)]PF6 (5c) was also prepared. A neutral homotrinuclear Rh-3 complex, [Rh-3(mu-Cl)(3)(mu-dpmppp)(CO)(2)] (6), was synthesized by the reaction of [RhCl(CO)(2)](2) with dpmppp and was further reacted with HgX2 (X = Cl, Br, I) to afford the Rh3Hg tetranuclear complexes [Rh-3(HgX)(mu-Cl)(2)(mu-X)(mu-dpmppp)(CO)(2)]PF6 (X = Cl (7a), Br (7b), I (7c)), where the Rh-3(mu-Cl)(2)(mu-X) cores act as tridentate ligands to form three donor-acceptor Rh -> Hg interactions. The two CO ligands of 7a-c were replaced by XylNC to yield [Rh-3(HgX)(mu-Cl)(2)(mu-X)(mu-dpmppp)(XylNC)(2)]PF6 (X = Cl (8a), Br (8b), I (8c)). The isocyanides had an appreciable influence on the three Rh -> Hg interactions, which was monitored by the (2)J(Hgp) values observed in the P-31{H-1} NMR spectra and discussed on the basis of DFT calculations. Complex 6 also reacted with CuCl and HBF4 to give [Rh-3(CuCl)(mu-Cl)(3)(mu-dpmppp)(CO)(2)] (9) and [Rh-3(mu(3)-H)(mu-Cl)(3)(mu-dpmppp)(CO)(2)]BF4 (10), respectively. These results suggested that the new tetraphosphine dpmppm proved quite useful in constructing fine-tunable heterometallic frameworks.
