The synthesis of 2-(N-aryolamino)benzothiazoles and 2-(N-aryolamino)benzimidazoles has been accomplished in the presence of copper catalyst. These reactions involve C-S and C-N cross-coupling reaction. All electron donating and withdrawing substituent's readily underwent the reaction to give target products in good to excellent yield. In addition, the reaction also gave target product in high yield
2-(N-芳基氨基)苯并噻唑和2-(N-芳基氨基)苯并咪唑的合成已在铜催化剂的存在下完成。这些反应涉及CS和CN交叉偶联反应。所有给电子和吸电子的取代基都容易进行反应,从而以良好或优异的产率得到目标产物。另外,该反应还以高产率批量生产目标产物。
