Ni-catalyzed reductive approach to the cross-coupling of two unactivated alkyl halides has been successfully developed. The reaction works efficiently for primary and secondary halides, with at least one being bromide. The mildreaction conditions allow for excellent functional group tolerance and provide the C(sp3)−C(sp3) coupling products in moderate to excellent yields.

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
