A Ni-catalyzed Negishi cross-coupling with 1,1-disubstituted styrenyl aziridines delivers valuable β-substituted phenethylamines via a challenging reductive elimination that affords a quaternary carbon. An electron-deficient olefin ligand is crucial for achieving high rates and chemoselectivity for C-C bond formation over β-H elimination.
