Heating of [(COD)M(κ2-3-PiPr2-2-NMe2-indene)]+X- (M = Rh or Ir; X = BF4, PF6; COD = η4-1,5-cyclooctadiene) in a mixture of water and THF (48 h, 60 °C) afforded the neutral (COD)M(κ2-P,O) complexes (M = Rh, 5a, 80%; M = Ir, 5b, 74%). Similarly, thermolysis of [(COD)M(κ2-3-P(S)iPr2-2-NMe2-indene)]+BF4- (M = Rh or Ir) in a mixture of water and CH2Cl2 (14 h, 60 °C) produced the neutral (COD)M(κ2-P(S),O) complexes
