The transition-metal-catalyzed α-arylation of secondary amides remains a synthetic challenge due to the presence of a free N–H bond. We report a strategy to synthesize secondary α-aryl amides via a Ni-catalyzed reductive arylation of redox-active N-hydroxyphthalimide (NHP) esters of malonic acid half amides. This transformation proceeds under mild conditions and displays excellent chemoselectivity
