The oxygenation of the electron-rich triple bond in the complexes [Re 2 X 4 (µ-dppm) 2 ][X = Cl or Br; dppm = bis(diphenylphosphino)methane]. Multielectron redox behaviour involving retention of the Re 2 X 4 P 4 unit Academic Article uri icon


  • The reactions of the triply bonded complexes [Re2X 4(μ-dppm)2] (X = Cl or Br; dppm = Ph 2PCH2PPh2) with O2 proceed to give the products [Re2(μ-O)(μ-X)(O)X3(μ-dppm) 2] and [Re2(μ-O)(O)2X4(dppm) 2] in high yield in which net four- and six-electron redox reactions have occurred and the integrity of the ligand sets of the precursor complex is preserved.
