efficient and simple coupling reactions of benzylic and aryl bromides with aluminium acetylide catalyzed by NiCl(2)(PPh(3))(2) are reported. The coupling reactions proceed at room temperature employing 4 mol% catalyst, affording coupling products in excellent yields of up to 95% in short reaction times. The system worked efficiently with aryl and heterocyclic bromides as well.
报告了高效和简单的苄基和芳基溴与NiCl(2)(PPh(3))(2)催化的乙炔铝偶联反应。偶联反应在室温下使用4 mol%的催化剂进行,在短的反应时间内以高达95%的优异收率提供偶联产物。该系统也可以有效地与芳基和杂环溴化物一起使用。
