and elemental analysis techniques. These palladium(II)‐NHC complexes were tested as efficient catalysts in the direct C—H bond activation of benzoxazole and benzothiazole with aryl bromides in the presence of 1 mol% catalyst loading at 150 °C for 4 h. Under the given conditions, various aryl bromides were successfully applied as the arylating reagents to achieve the 2‐arylbenzoxazoles and 2‐arylbenzothiazoles
在此,我们报道了一系列新颖的
钯(II)-NHC配合物(NHC = N-杂环卡宾)。所有新型配合物的结构均通过1 H NMR,13 C NMR,FT-IR光谱和元素分析技术表征。这些
钯(II)-NHC络合物在1 mol%的催化剂负载量下,在150°C的条件下,在苯甲唑和
苯并噻唑与芳基
溴的直接C-H键活化中进行了4小时测试,作为有效的催化剂。在给定的条件下,各种芳基
溴已成功地用作芳基化试剂,以可接受的高收率获得了2-芳基
苯并恶唑和2-芳基
苯并噻唑。
