摘要：

Complex 1 undergoes H/D scrambling in methanol without concomitant liberation of either methane or dihydrogen (kH/kD = 0.76, 55 °C). The measured isotope effect was proposed to directly relate to the initial reductive coupling step in reductive elimination reactions. Copyright © 2002 American Chemical Society.
