A mild cobalt-catalyzed Negishi-type cross-coupling of various functionalized dialkylzinc reagents with primary and secondary alkyl iodides in acetonitrile is reported using a combination of 20% CoCl2 and chelating nitrogen ligands. The method allows the construction of molecules with alkyl chains bearing sensitive functional groups at room temperature.
