TpPt(IV)Me(H)2 Forms a σ-CH4 Complex That Is Kinetically Resistant to Methane Liberation

Complex 1 undergoes H/D scrambling in methanol without concomitant liberation of either methane or dihydrogen (k H/k D = 0.76, 55 °C). The measured isotope effect was proposed to directly relate to the initial reductive coupling step in reductive elimination reactions.
