Popis: | The reactions of [MH(CO)(PPh3)3] (M = Rh or Ir) with anhydrous HF or HBF4 · Et2O lead to completely different products. With an excess of acid, when M = Ir, oxidation gives [IrH2(CO)(PPh3)3][X](X = HF2, BF4), whereas, when M = Rh, dissociation of a ligand and elimination of hydrogen gas gives a 1:1 mixture of [Rh(CO)(PPh3)2(solv.)][X] and [HPPh3][X] (X = HF2, BF4). With a deficit of acid, [Rh(CO)(PPh3)3][X] is also generated which, for X = BF4, has been crystallographically characterised. |
