EPOXYDATION EN MILIEU HETEROGENE SOLIDE-LIQUIDE: EFFET DES INTERACTIONS A L'INTERFACE SUR LA STABILITE DE L'YLURE DE DIMETHYLSULFONIUM - CONSEQUENCES SUR LA STEREOCHIMIE DE LA REACTION D'EPOXYDATION

The use of solid-liquid heterogenous system in a low hydrated organic medium during the epoxidation reaction of rigid cyclohexanones stabilizes the dimethylsulfonium ylide.The stereochemistry of the reaction is then modified and results to be different from the one obtained in an anhydrous homogeneous medium.However the ylide stability is not sufficient to lead to a cyclopropyl by-product with the α-ionone.
