Kinetic investigations on the insertion of metal-carbenoid intermediates into the Si-H bond have been carried out. A kinetic isotope effect of 1.5 was found and the plot of log kx/krt vs cr for the reaction of arylsilanes with EDA, gave a straight line with p =-0.31. It was thus concluded that the i

An internal competition was used to estimate the kinetic isotope effect of an intramolecular metal carbene C-H insertion reaction alpha to a nitrogen atom. A stereoelectronic effect is proposed to explain the difference in magnitude of the observed KIEs for cis and trans diastereomers.
