A ligand-controlled, nickel-catalyzed cross-coupling of aliphatic N-tosylaziridines with aliphatic organozinc reagents offers complete regioselectivity for reaction at the less hindered C-N bond, and the products are furnished in very good yield for a broad selection of substrates. The air-stable nickel(II) chloride/ligand precatalyst can be handled and stored outside a glovebox.
