useful surrogates for alkylhalides in cross‐coupling chemistry. Such esters are easily accessible through reactions between ubiquitous carboxylic acids and coupling agents widely used in amide bond formation. This article features an amalgamation of in‐house experience bolstered by approximately 200 systematically designed experiments to accelerate the selection of ideal reaction conditions and activating

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.
