초록/해제  
요약Utilizing primary amines as alkyl coupling partners has garnered attention in recent years due to their widespread availability, facile preparation and purification, and presence in a variety of common building blocks. The reemergence of Katritzky salts has enabled deaminative alkylation and arylation of α-1° and α-2° amines. The Rovis group has developed deaminative conditions for α-3° amines utilizing redox-active imines to generate tertiary carbon-centered radicals. Herein, we couple this tertiary alkyl radical to haloarenes to generate benzylic quaternary centers, a common motif in pharmaceuticals and natural products. We then applied this methodology in the realm of isotopic exchange to generate 15N-primary amines from their naturally occurring 14N-analogues. By activating α-1° and α-2° amines to Katritzky pyridinium salts and α−3° amines to redox-active imines, we can engage primary alkyl amines in a late-stage isotopic exchange with complete and selective isotopic labelling.
