摘要: 2,5-Diaryl-substituted furans were synthesized from the copper-catalyzed decarboxylative coupling of aryl-substituted aryl propiolic acids in presence H2O. The homocoupling alkynyl carboxylic provided 1,4-diaryldiynes, which then reacted with H2O to give desired through cyclization. Addition copper catalyst was critical, and addition a ligand increased yield products both cyclization reactions. In addition, thiophenes could be obtained when reaction conducted Na2S.
