摘要：
An efficient potassium carbonate and copper-mediated C-S and C-N 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.
