A novel halogenation reaction from sulfonates catalyzed by iron(III) is described. The reaction can be performed as a stoichiometric or a catalytic version. This reaction provides a convenient strategy for the efficient access to structurally diverse secondary chlorides, bromides and iodides. The stereochemical course of the reaction is governed by the substrate and the experimental conditions. Secondary
描述了由铁(III)催化的磺酸盐的新型卤化反应。该反应可以化学计量形式或催化形式进行。该反应为有效地获得结构上多样的仲氯化物,溴化物和碘化物提供了便利的策略。反应的立体化学过程取决于底物和实验条件。改性为堂基化物或pysylates的仲醇具有更高的反应性。脂肪族基磺酸盐在催化条件下进行构型的整体转化。观察到二甲磺酸酯的化学选择性有利于仲甲磺酸酯。另外,基于实验结果,已经提出了卤化的可能的催化循环。
