  Approaches to bi- and trimetallic platinum and palladium complexes using the DPPEPM ligand

  摘要：

  Bis {(diphenylphosphinoethyl)phenylphosphino}methane (DPPEPM) reacts with [PtR2(cod)] in 1:1 ratio to give [PtR2? (DPPEPM-PP)] (2a, R = Me; 2b, R = Ph), whereas with [PtCl2(cod)] or [PdCl2(cod)] it yields the ionic species [M(DPPEPM-PP)(2)](2+) (3 and 4). With [MClMe(cod)], the product is [MMe(DPPEPM-PPP)](+) (5, M Pt; 6, M = Pd), in which one of the internal P atoms of the ligand is uncoordinated. These complexes undergo oxidation of the free P atom to give 7 and 8 on standing in solution. Complexes 2-4 may be used to construct bimetallic and trimetallic mixed metal complexes. The molecular structures of 7 and [PtMe2(mu-DPPEPM)PdCl2] (11) are reported. (C) 2003 Elsevier B.V. All rights reserved.

  The reaction of meso-DPPEPM (DPPEPM = bis(diphenylphosphino-ethylphenylphosphino)methane) with one equivalent of FeBr2 in tetrahydrofuran generates a zwitterionic compound [FeBr(κ2-DPPEPM)(κ3-DPPEPM-FeBr3)] (1). Compound 1 exhibits an unusual bonding arrangement with two meso-DPPEPM ligands and one bromide coordinated to a single Fe(II) center. One of the DPPEPM ligands binds to iron in a κ2 mode via two central phosphorus atoms, leaving the terminal phosphines dangling. The second DPPEPM binds through three phosphines, whereas the fourth one coordinates to the iron center of an external FeBr3− unit. A 1 : 2 reaction of FeBr2 and meso-DPPEPM in tetrahydrofuran generates [FeBr(κ2-DPPEPM)(κ3-DPPEPM)]Br ([2]Br) in which the positive charge on the pseudo-octahedral unit is balanced by free Br− as opposed to the phosphine-bound FeBr3− in 1. The compound [2]PF66 was obtained from [2]Br and TlPF6. Solution structures for 1, [2]Br and [2]PF66 were assigned on the basis of 31P NMR. For all three compounds the data are consistent with five phosphorus atoms bound to the metal.

  The tetraphosphine DPPEPM reacts with [PtMe2(cod)] to produce [PtMe2(DPPEPM-PP)] (1) in near quantitative yield. On standing in solution, the free P atoms become oxidized to give [PtMe2(DPPEPM(O)(2)-PP)] (1a), which has been characterized by X-ray crystallography. In contrast, reactions of DPPEPM with [MCl2(cod)] (M = Pd, Pt) yield ionic products of the form [M(DPPEPM-PP)2]MC]4 (3, 4). When a solution of the platinum complex was allowed to stand, crystals of [Pt(mu-Cl)(mu-DPPEPM)(2)]Cl-3 (5) were obtained. In a third set of reactions, treatment of [PtCIR(cod)] (R = Me, Ph) or [PdClMe(cod)] with DPPEPM gives species of the type [MR(DPPEPM-PPP)]Cl (6-8), in which one of the internal P atoms is uncoordinated. Reactions of [PtR2(DPPEPM-PP)] with [PtR2'(cod)] or [MCl2(Cod)] (M = Pd, Pt), or of [PtR(DPPEPM-PPP)]Cl with [MCl2(cod)], lead to unsymmetrical bimetallic complexes. [PtMe2(mu-DPPEPM)PdCl2] (11) and [PtClPh(mu-DPPEPM)PdCl2] (14) have been characterized crystallographically. Trimetallic complexes of the form [PtR2(mu-DPPEPM)}(2)M][MCl4] (M = Pd, Pt, 15-17) are produced by reaction of [PtR2(DPPEPM-PP)] with [MCl2(cod)]. (c) 2005 Elsevier B.V. All rights reserved.
