general, high-yielding amine Cα–H cyanation protocol via photoredox catalysis. Inexpensive NaCN is employed as the cyanidesource and air is the external oxidant, resulting in mild and highly functional group tolerant conditions. Notably, efficient Cα–H cyanations of secondary and tertiary aliphatic amines and of complex, biologically active compounds (drugs) can be performed using the established methodology

cyanation of tertiary amines and its application in late-stage functionalization. Suitable substrates include tertiary aliphatic, benzylic, and aniline-type substrates and complex substrates. Functional groups tolerated under the reaction conditions include various heterocycles and ketones, amides, olefins, and alkynes. This broad substrate scope is remarkable, as comparable reaction protocols for

precious metal catalyzed, oxidative protocols to generate such functionalities. However, simple tertiary alkyl amines cannot be used as starting materials in these protocols. The research described herein enables the oxidative synthesis of amides from simple, noncyclic tertiary alkyl amines under synthetically useful, mild conditions through a biologically inspired approach: Fe‐catalyzed CαH functionalization

Oxidation at the sulfur of the safe-to-handle potassium thiocyanate releases cyanide units that are trapped in the presence of co-oxidized tertiaryamines to form α-amino nitriles. These cyanations work in aqueous solutions and do not require a catalyst, nor do they form toxic byproducts.
