Synthesis of\nPrimary and Secondary Amines via Electrochemical\nReduction of Hydrazines

We herein introduce an electrochemical route for the\nN–N\nbond cleavage of hydrazines. This mild and green methodology utilized\nreadily available mono- and 1,1-disubstituted hydrazines or their\nHCl salts as starting materials to access a broad scope of primary\nand secondary amines in high yields. The mechanistic investigation\nsuggests that the amine product is formed by consecutive SET reduction,\nand utilization of a hydrazine HCl salt is important for providing\nsufficient conductivity and acidity to facilitate this reaction.
