An environmentally benign catalyst, the N,N′-dioxide–FeCl3 complex, has been developed for the asymmetric intramolecular Cannizzaro reaction with high yields and enantioselectivities.

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
