摘要：

The reaction of IrX(CO)(dppe) (X = Br, I; dppe = 1,2-bis(diphenylphosphino)ethane) with Cp2TaH3 (Cp = η5-cyclopentadienyl) is extremely rapid and leads to clean formation of fac-IrH3(CO)(dppe) and Cp2TaX, or Cp2TaXL (L = CO, C2H4, C3H7C≡ CC3H7) in the presence of added ligand. Trapping and isotope-labeling experiments indicate that the reaction does not proceed through production of free IrH2X(CO)(dppe), [IrH(CO)(dppe)], or [Cp2TaH]. the results are consistent with formation of unstable hydride and halide-bridged binuclear intermediates, in which transfer of all hydride and halide ligands occurs before fragmentation into mononuclear species. © 1990 American Chemical Society.
