Added value: A copper‐based method is highly efficient for the cross‐coupling of alkyl electrophiles with secondary and tertiary alkylGrignardreagents. The method is distinguished by its broad substrate scope and high functional group tolerance.

The formation of C(sp3)–C(sp3) bonds by cross-coupling remains a challenge in synthesis. Here, we demonstrate a two-step, one-pot protocol for the in situ generation of N-hydroxyphthalimide esters and their nickel-catalyzed cross-electrophile coupling with unactivated alkyl bromides for the construction of 1°/1 ° C(sp3)–C(sp3) bonds. The conditions tolerate an array of functional groups, and mechanistic
