  名称：

  Four-membered chelate rings in complexes with 2,2-bis(diphenylphosphino)propane. Crystal and molecular structures of trans-[RuCl₂{Me₂C(PPh₂)₂}₂], [RuCl{Me₂C(PPh₂)₂}(η-C₅H₅)] and [(η-C₅H₅)Ru(µ-CO)₂-{µ-Me₂C(PPh₂)₂}RhCl₂](Rh–Ru)

  摘要：

  The compound Me(2)C(PPh(2))(2) (2,2-dppp) reacted with 0.5 equivalent of [Rh2Cl2(CO)(4)] to afford monomeric [RhCl(CO)(2.2-dppp-P,P')] 1. Metathesis with LiBr afforded [RhBr(CO)(2.2-dppp-P,P')] 2. With 0.25 equivalent of [Rh2Cl2(CO)(4)] the rigid, square-planar [Rh(2,2-dppm)(2)]Cl 3 was formed. These results are in sharp contrast to the chemistry seen with H2C(PPh(2))(2) and H(Me)C(PPh(2))(2). With 0.5 equivalent of [RuCl2(PPh(3))(3)], 2,2-dppp reacted to give brown-orange trans-[RuCl2(2,2-dppp)(2)] 4a. In solution this is in equilibrium with a green five-co-ordinate species [RuCl(2,2-dppp)(2)]Cl 4b, the first such complex to be observed with a four-membered chelating diphosphine. With [RuCl(PPh(3))(2)(eta-C5H5)], 2,2-dppp reacted to form [RuCl(2,2-dppp)(eta-C5H5)] 5. Although its rhodium(I) chemistry suggests that 2,2-dppp favours chelation rather than bridging modes of co-ordination, when 5 was treated with 0.5 equivalent of [Rh2Cl2(CO)(4)] it readily formed [(eta-C5H5)Ru(mu-Co)(2)(mu-2,2-dppp)RhCl2](Rh-Ru) 6. The structures of 4-6 have been determined by X-ray diffraction.
