• Tetrabutylammonium Salt Induced Denitration of Nitropyridines:  Synthesis of Fluoro-, Hydroxy-, and Methoxypyridines
  作者：Scott D. Kuduk、Robert M. DiPardo、Mark G. Bock

  DOI：10.1021/ol047688v

  日期：2005.2.1

  An efficient method for the synthesis of fluoropyridines via the fluorodenitration reaction is reported. The reaction is mediated by tetrabutylammonium fluoride (TBAF) under mild conditions without undue regard to the presence of water. The fluorodenitration is general for 2- or 4-nitro-substituted pyridines, while 3-nitropyridines require attendant electron-withdrawing groups for the reaction to proceed

  报道了一种通过氟脱硝反应合成氟吡啶的有效方法。反应在温和的条件下由四丁基氟化铵（TBAF）介导，而无需过多考虑水的存在。对于2-或4-硝基取代的吡啶，通常进行氟脱硝，而3-硝基吡啶需要伴随的吸电子基团以使反应有效地进行。硝基吡啶在相应的四丁基铵物质存在下，在温和的条件下也会进行羟基-和甲氧基的脱硝反应。[反应：看文字]
