• Ligand-, Copper-, and Amine-Free Sonogashira Reaction of Aryl Iodides and Bromides with Terminal Alkynes
  作者：Sameer Urgaonkar、John G. Verkade

  DOI：10.1021/jo049325e

  日期：2004.8.1

  and amine-free palladium-catalyzed Sonogashira reaction of aryl iodides and bromides with terminal alkynes have been developed. Critical to the success of this new protocol is the use of tetrabutylammonium acetate as the base. Noteworthy features of this method are room-temperature conditions and the tolerance of a broad range of functional groups in both reaction partners.

  已经开发出有效的无配体，无铜和无胺的钯催化的芳基碘化物和溴化物与末端炔烃的Sonogashira反应的条件。该新方案成功的关键是使用乙酸四丁铵作为碱。该方法的显着特征是室温条件和两个反应伙伴中多种官能团的耐受性。
• Sonogashira Coupling Using Bulky Palladium-Phenanthryl Imidazolium Carbene Catalysis

  日期：2003.9.1

  [GRAPHICS]Bulky phenanthracenyl imidazolium-derived carbene ligands were investigated for copper-free Sonogashira coupling with terminal acetylenes. Aryl bromides and iodides gave coupled products in excellent yields from the Pd(PPh3)(2)Cl-2 complex with potassium t-butoxide and 18-crown-6 in THF. A remarkable dependence on the size of the ligand was found. The highest yields were obtained with the bulky 2,9-dicyclohexyl-10-phenanthryl ligand 5.
• High throughput evaluation of the production of substituted acetylenes by the Sonogashira reaction followed by the Mizoroki–Heck reaction in ionic liquids, in situ, using a novel array reactor

  日期：2006.4

  The parallel Sonogashira coupling reaction was carried out under copper-free condition by integrating the advantages of ionic liquids as the reaction media followed by the simultaneous-multiple Mizoroki-Heck reaction in Situ by the use of a novel array reactor (SynArray-24). The device provides rapid evaluation of reactions in a short period. (c) 2006 Elsevier Ltd. All rights reserved.
