Catalytic Action of Azolium Salts. IX. Synthesis of 6-Aroyl-9H-purines and Their Analogues by Nucleophilic Aroylation Catalyzed by Imidazolium or Benzimidazolium Salt.
Preparation of Heteroarenecarbonitriles by Reaction of Haloheteroarenes with Potassium Cyanide Catalyzed by Sodium p-Toluenesulfinate
摘要:
Several heteroarenecarbonitriles were prepared by reaction of haloheteroarenes with potassium cyanide catalyzed by sodium p-toluenesulfinate (1) or sodium methanesulfinate (2). In the reaction pathway, the cyanation proceeds through the formation of the sulfonylheteroarenes.
