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
