摘要：

An efficient preparation of a new recyclable polymer-supported oxidizing agent based on N-phenylsulfonyloxaziridine has been developed. This new polymer-supported oxidant was shown to effect a clean and selective conversion of a range of sulfides, selenides, amines, phosphines and enolates to the corresponding sulfoxides, selenoxides, N-oxides, phosphine oxides and alpha-hydroxy carbonyl compounds. It also enabled tetrahydrobenzimidazoles to be oxidatively rearranged to spiro-fused 5-imidazolones. Recycling of the polymer-supported oxidant is possible with minimal loss of activity after several re-oxidations.
