Potassium N-heterobiaryltrifluoroborates were successfully prepared via a selective Cu-catalyzed C-N coupling reaction. The BF3K moiety was well tolerated under the reaction conditions involving CuI and dimethylethylenediamine (DMEDA) in the presence of DMSO. The Pd-catalyzed Suzuki-Miyaura cross couplings of potassium N-heterobiaryltrifluoroborates with bromoarenes were studied to prepare the N-heterotriaryl
通过选择性Cu催化的CN偶联反应成功制备了N-杂二芳基三氟硼酸钾。在 DMSO 存在下,在涉及 CuI 和二甲基乙二胺 (DMEDA) 的反应条件下,BF3K 部分具有良好的耐受性。研究了Pd催化的N-杂二芳基三氟硼酸钾与溴代芳烃的Suzuki-Miyaura交叉偶联制备N-杂三芳基化合物。此外,N-杂二芳基三氟硼酸钾的同源偶联、碘化和羟基化以高产率提供了相应的产物。
