3-Carboxypyridinium chlorochromate (CPCC) in the presence of aluminium chloride is a very efficient reagent for the selective oxidation of sulfides to sulfoxide and sulfones in solution and under microwave irradiation. It is noteworthy that different functional groups including carbon–carbon double bonds, ketones, oximes, aldehydes, ethers, and acetals were tolerated under these reaction conditions.Key words: sulfoxides, sulfones, oxidation, chlorochromate, Lewis acid.

Le chlorochromate de 3-carboxypyridinium (CCCP) en présence de chlorure d'aluminium est un réactif très efficace pour l'oxydation des sulfures en sulfoxydes et en sulfones effectuée en solution et sous irradiation de micro-ondes. Il est notable que divers groupes fonctionnels, y compris les doubles liaisons carbone–carbone, les cétones, les oximes, les aldéhydes, les éthers et les acétals, sont tolérés dans les conditions de la réaction.Mots clés : sulfoxydes, sulfones, oxydation, chlorochromate, acide de Lewis.[Traduit par la Rédaction]
