• Graphite/Methanesulfonic Acid (GMA) as a New Reagent for Sulfonylation of Phenols and Thia-Fries Rearrangement of Aryl Sulfonates to Sulfonylphenols
  作者：Hashem Sharghi、Zahra Shahsavari-Fard

  DOI：10.1002/hlca.200490295

  日期：2005.1

  A new facile method for direct sulfonylation of phenols was developed. Graphite in methanesulfonic acid (GMA) was used to prepare sulfonylphenols by sulfonylation of phenol and naphthalene derivatives with p-toluenesulfonic acid (=4-methylbenzenesulfonic acid) (Table 1) and the thia-Fries rearrangement of aryl sulfonates (Table 4). Mechanistic studies showed that the sulfonylation reaction of phenols

  开发了一种新的直接苯酚磺酰化的简便方法。使用甲磺酸中的石墨（GMA）通过苯酚和萘衍生物与对甲苯磺酸（= 4-甲基苯磺酸）（表1）进行磺酰化以及芳基磺酸盐的硫-弗里斯重排（表4）来制备磺酰基苯酚。机理研究表明，GMA中苯酚的磺酰化反应是通过最初的磺酸盐形成，然后通过分子间机理使芳基磺酸盐的硫-弗里斯重排而发生的（方案3）。
