  Copper-catalyzed oxidative C‒H, N‒H coupling of azoles and thiophenes

  摘要：

  C-H, N-H coupling of azole and thiophene derivatives takes place in the presence of a catalytic amount of Cu(OAc)(2) and an additive. The reaction of azoles smoothly occurs with several amines and amides catalyzed by 20 mol % of Cu(OAc)(2)-2PPh(3) and 4 equiv of NaOAc under O-2 or in the presence of Ag2CO3 under N-2. The coupling reaction leads to a facile synthesis of a N-substituted analogue of 2,5-diarylthiazole, which shows photoluminescent properties with extended pi-conjugation. Spectroscopic characteristics of the obtained thiazole derivatives are discussed by measurements of UV-vis absorption and photoluminescent spectra. Under the reaction conditions using Ag2CO3 as an additive and Cu(OAc)2-2PPh3 as a catalyst, thiophene derivatives also react with 2-pyrrolidone to undergo C-H, N-H amidation. (C) 2012 Elsevier Ltd.

  C-H, N-H coupling of azole and thiophene derivatives takes place in the presence of a catalytic amount of Cu(OAc)(2) and an additive. The reaction of azoles smoothly occurs with several amines and amides catalyzed by 20 mol % of Cu(OAc)(2)-2PPh(3) and 4 equiv of NaOAc under O-2 or in the presence of Ag2CO3 under N-2. The coupling reaction leads to a facile synthesis of a N-substituted analogue of 2,5-diarylthiazole, which shows photoluminescent properties with extended pi-conjugation. Spectroscopic characteristics of the obtained thiazole derivatives are discussed by measurements of UV-vis absorption and photoluminescent spectra. Under the reaction conditions using Ag2CO3 as an additive and Cu(OAc)2-2PPh3 as a catalyst, thiophene derivatives also react with 2-pyrrolidone to undergo C-H, N-H amidation. (C) 2012 Elsevier Ltd.
