A catalytic Mitsunobu reaction system is described in which the azo reagent is used as an organocatalyst and iodosobenzene diacetate is used as the stoichiometric oxidant. In this system, iodosobenzene diacetate oxidizes the formed hydrazine byproduct to regenerate the azo reagent. Yields obtained in the catalytic reactions using a variety of carboxylic acids and alcohols were slightly lower than those
描述了一种催化性的 Mitsunobu 反应系统,其中偶氮试剂用作有机催化剂,碘代苯二乙酸酯用作化学计量氧化剂。在该系统中,碘代苯二乙酸盐氧化形成的肼副产物以再生偶氮试剂。在使用各种羧酸和醇的催化反应中获得的产率略低于从相应化学计量反应获得的产率。伯醇和仲醇都可以用作该反应体系中的底物,仲醇在甲醇中心提供具有倒立立体化学的产物。
