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.

In the presence of Bu4NI (3 equiv) and 4-fluorostyrene (20 mol %), unreactive primary and secondary alkylzinc iodides undergo nickel-catalyzed cross-couplings with various primary alkyl iodides or bromides. More reactive secondary dialkylzincs and the mixed zinc organometallics RZnTMSM undergo the cross-coupling reaction in the absence of Bu4NI. The bicyclic secondary diorganozinc 6 prepared via boron-zinc exchange reacts with high retention of configuration. Free NH-groups are tolerated in the cross-coupling allowing the synthesis of aminated products.
