An efficient potassium carbonate and copper-mediated CS and CN Ullmann coupling reaction between 2-bromothiophenol and 2-haloacetanilide is reported here. This protocol affords a simple and efficient approach for the construction of 1,4-benzothiazinone-3-one derivatives, avoiding the limitations of using noble metals and expensive ligands for the first time.
本文报道了 2-溴苯硫酚和 2-卤代乙酰苯胺之间有效的碳酸钾和铜介导的 C S 和 C N Ullmann 偶联反应。该方案为构建 1,4-苯并噻嗪酮-3-酮衍生物提供了一种简单有效的方法,首次避免了使用贵金属和昂贵配体的限制。
