Scope of the amide substrate. (Conditions, unless otherwise stated: Ni(cod)2, 10 mol %; SIPr, 10 mol %; substrate, 1.0 equiv; benzylzinc bromide (5), 1.5 equiv; and THF, 1.0 M at 23 °C for 24 h. Yields shown reflect the average of two isolation experiments. The superscripted symbol “a” in the figure denotes that the corresponding N-Bn,Boc benzamide derivative was used.)
