This paper reports an efficient synthesis of triphenylamine (TPA) derivatives via a palladium-catalyzed Suzuki reaction of (hetero)aryl halides with 4-(diphenylamino)phenylboronic acid (DPBA) in aqueous ethanol under aerobic and ligand-free conditions. Heteroaryl halides, namely pyridyl bromides, quinolyl bromides, pyrimidinyl bromides, 2-chloropyrazine and sulfur-containing heteroaryl bromides, could
本文报告了一个有效的综合 三苯胺(TPA)衍生物通过(杂)芳基卤化物与4-(二苯氨基)苯基硼酸(DPBA)水溶液乙醇在无氧和无配体的条件下。杂芳基卤化物,即吡啶基溴化物,喹啉基溴化物,嘧啶基溴化物,2-氯吡嗪含硫杂芳基溴化物可以与DPBA平稳反应,在温和条件下收率好至极好。此外,芳基溴化物也成功地用于与DPBA的交叉偶联中,并在室温下以高收率提供了产品。的交叉耦合4-溴苄腈与DPBA一起使用,在2分钟内以定量收率得到了所需的产物,导致TOF高达5820 h -1。
