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 carboncarbon double bonds, ketones, oximes, aldehydes, ethers, and acetals were tolerated under these reaction conditions.Key words: sulfoxides, sulfones, oxidation, chlorochromate, Lewis acid.
3-羧基吡啶氯铬酸铵(CPCC)在铝氯化物存在下是一种非常有效的试剂,可在溶液中并在微波辐射下选择性氧化硫化物为亚砜和砜。值得注意的是,在这些反应条件下,不同的官能团,包括碳-碳双键、酮、肟、醛、醚和缩醛都能耐受。关键词:亚砜、砜、氧化、氯铬酸铵、Lewis酸。
