Secondary alicyclic amines are converted to α-aminonitriles via addition of TMSCN to their corresponding imines, intermediates that are produced in situ via the oxidation of amine-derived lithium amides with simple ketone oxidants. Amines with an existing α-substituent undergo regioselective α′-cyanation even if the C–H bonds at that site are less activated. Amine α-arylation can be combined with α′-cyanation
