Six-membered cyclic α-aminonitriles were prepared fromanodic cyanation of N-benzylpiperidine. Low current, CH3OH/H2O and CH3CN/H2O used as solvent, tetraammonia salt such as Et4NOTs and Et4NBr used as surfactant are propitious to the reaction under constant current electrolysis. Graphite as anode can give the similar result to platinum. The potentiostatelectrolytic condition of 0.9~1.4 V (vs. SCE), low temperature and low substrate concentration offered good yields (above 90%) of α-aminonitriles. Themechanism of the reaction was studied and the amount of isomers was depended onthe adsorption status at the anode surface and stability of intermediate was also studied under potentiostat electrolysis.

Key words: anodic cyanation, electrolysis, N-benzylpiperidine, α-aminonitrile
