Efficient Csp3–Csp3 Suzuki couplings have been developed with both potassium cyclopropyl- and alkoxymethyltrifluoroborates. Moderate to good yields have been achieved in the cross-coupling of potassium cyclopropyltrifluoroborate with benzyl chlorides possessing electron-donating or electron-withdrawing substituents. Benzyl chloride was also successfully cross-coupled to potassium alkoxymethyltrifluoroborates
使用环丙基三氟硼酸钾和烷氧基甲基三氟硼酸钾开发了高效的 Csp 3 –Csp 3 Suzuki 偶联物。在环丙基三氟硼酸钾与具有给电子或吸电子取代基的苄基氯的交叉偶联中,已经实现了中等至良好的产率。苄基氯还成功地与衍生自伯醇、仲醇和叔醇的烷氧基甲基三氟硼酸钾交叉偶联。
