• Mild, efficient, and chemoselective dehydrogenation of 2-imidazolines, bis-imidazolines, and <i>N</i>-substituted-2-imidazolines with potassium permanganate supported on montmorillonite K-10
  作者：Iraj Mohammadpoor-Baltork、Mohammad Abdollahi-Alibeik

  DOI：10.1139/v04-171

  日期：2005.2.1

  Different types of 2-imidazolines, bis-imidazolines, and N-substituted-2-imidazolines are efficiently oxidized to their corresponding imidazoles with potassium permanganate (KMnO₄) supported on montmorillonite K-10 under very mild conditions. The procedure is very simple and no strict conditions were required. Selective dehydrogenation of 2-alkyl-2-imidazolines in the presence of 2-aryl-2-imidazolines is a noteworthy advantage of this method and can be considered as a useful practical achievement in these reactions.Key words: 2-imidazolines, imidazoles, dehydrogenation, potassium permanganate, montmorillonite K-10.

  不同类型的2-咪唑啉、双咪唑啉和N-取代的2-咪唑啉可以在蒙脱石K-10载体上使用高锰酸钾(KMnO₄)在非常温和的条件下高效氧化为它们相应的咪唑化合物。该方法非常简单，无需严格条件。在2-芳基-2-咪唑啉存在时选择性脱氢2-烷基-2-咪唑啉是该方法的一个显著优势，可以被视为这些反应中的一项有用的实际成就。关键词：2-咪唑啉、咪唑化合物、脱氢、高锰酸钾、蒙脱石K-10。

  日期：——

  A rapid, mild and high-yielding method for dehydrogenation of a variety of structurally diverse 2-imidazolines to imidazoles using trichloroisocyanuric acid (TCCA) in the presence of DBU is reported. Chemoselective oxidation of 2-imidazolines can be achieved in the presence of sulfide and alcohol. The mild conditions of this procedure and the absence of any transition metal make this reaction suitable for safe laboratory use.
