Measurements of the primarykinetichydrogenisotopeeffects for the intramolecular migration of hydride accompanying the rearrangements of (i) hydroxy-ketones involving 1,4-migration of hydride between ketonic carbonyl groups and (ii) phenylglyoxal hydrates to their corresponding mandelic acids are described. The results are discussed using abinitioMO calculations of model systems, with a variety
