Herein, we report a formal C–C bond azidation and cyanation of unactivated aliphatic ketones using commercially available tosyl azide cyanide, respectively. A visible-light-mediated organophotocatalyst enables radical ketone-derived pro-aromatic dihydroquinazolinones (under mostly redox-neutral conditions) as supported by preliminary mechanistic studies. These metal-free scalable protocols can be used to synthesize tertiary, secondary, primary alkyl azides nitriles with good functional group tolerance postsynthetic diversification the group, including bioconjugation.
