A room-temperature Ni-catalyzed reductive method for the coupling of aryl bromides with secondaryalkylbromides has been developed, providing C(sp2)–C(sp3) products in good to excellent yields. Slight modification of this protocol allows efficient coupling of activated aryl chlorides with cyclohexyl bromide and aryl bromides with allylic acetate.

coupling of aryl bromides and cyclic secondary alkylbromides catalyzed by nickel/spiro-bidentate-pyox ligands with lithium chloride as the additive for the Csp2–Csp3 bond formation was reported. The reaction could tolerate functional groups such as sulfonamide, ester, aldehyde, ketone, protected indolyl, tert-butoxycarbonyl, aryl nitriles and aryl chloride. Various aryl-cyclic secondary alkyl Csp2–Csp3 bond
