A secondary phosphine oxide (SPO)-nickel catalyst allowed the activation of otherwise inert C–F bonds of unactivated arenes in terms of challenging couplings with primary and secondary alkyl Grignard reagents. The C–F activation is characterized by mild reaction conditions and high levels of branched selectivity. Electron-rich and electron-deficient arenes were suitable electrophiles for this transformation
二级氧化膦(SPO)-镍催化剂可以活化未活化芳烃的惰性C-F键,这是与伯氏和仲烷基格氏试剂的偶合挑战。C–F活化的特征是反应条件温和和分支选择性高。富电子和电子不足的芳烃是适合这种转化的亲电试剂。此外,该策略还证明适用于杂环和在稍加修改的条件下活化C-O键的方法。
