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
