Abstract

This paper reports a room temperature, nickel-catalyzed Negishi cross-coupling of N-acylsuccinimides with arylzinc reagents via selective N–C bond cleavage enabled by amide bond twist. The reaction proceeds using a commercially available, air-stable Ni(II) precatalyst in the absence of additives under exceedingly mild conditions. Of broad interest, this report introduces N-acylsuccinimides as stable, crystalline, electrophilic, cost-effective, benign, amide-based acyl transfer reagents via acyl metal intermediates. The reaction selectivity is governed by half-twist of the amide bond in N-acylsuccinimides, thus opening the door for applications in metal-catalyzed manifolds via redox­-neutral reaction pathways tuneable by amide bond distortion.
