Transition metal-free electrochemical approaches for the N-cyanation of secondaryamines and the α C-cyanation of tertiaryamines have been well established, with products being obtained in moderate to good yields and with good functional group tolerance under ambient conditions. The synthetic application of the protocols has been highlighted through scale-up experiments in a galvanostatic mode. Preliminary

)−H Bond of Tetrahydroisoquinolines through C−H Activation Relay (CHAR) Using α‐Cyanotetrahydroisoquinolines as Starting Materials
Using α-cyanotetrahydroisoquinolines as the startingmaterials, a TBN/O2 initiated C(sp3)−Hbondmultifunctionalization was developed, realizing the construction of the isoquinolin-1-one skeleton. This work revealed that the functionalization of the relatively inert C−Hbond could be induced by a radical C−Hactivationrelay (CHAR) process.
