The mechanism of the anomalous intramolecular insertion reaction of a rhodium carbenoid into an ethereal C-H bond has been explored using deuterium labelled substrates. Comparison of primary kinetic isotope effects and analysis of ratios of diastereoisomeric deuterated products suggests the reaction
