  日期：2016.5.6

  By the use of 1-chloro-1,2-benziodoxol-3-one, an age-old reagent, the practical and efficient chlorination method is achieved. This hypervalent iodine reagent is amenable not only to the chlorination of nitrogen-containing heterocycles but also to selected classes of arenes, BODIPY dyes, and pharmaceuticals. In addition, the advantages, such as easy preparation and recyclable, air- and moisture-stable

  通过使用一种古老的试剂1-chloro-1,2-benziodoxol-3-one，可以实现一种实用而有效的氯化方法。这种高价碘试剂不仅适用于含氮杂环的氯化反应，而且适用于某些类别的芳烃，BODIPY染料和药物。另外，诸如易于制备和可回收利用，对空气和水分稳定的优点等优点，以及在克级实验中的成功，使该试剂具有巨大的工业应用潜力。
