用环丙基钾和三氟硼酸alkoxymethyltrifluoroborates开发了高效的Csp3-Csp3 Suzuki偶联。三氟硼酸环丙基钾与具有供电子或吸电子取代基的苄基氯化物的交叉偶联反应获得了中等到较好的产率。氯化苄还成功地与由伯、仲、叔醇衍生的烷氧甲基三氟硼酸钾交叉偶联。
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 derived from primary, secondary, and tertiary alcohols.
