Abstract

Described are processes for producing amines from nitriles. The processes include electrocatalytic hydrogenations of nitriles in the presence of transition metal-oxide and/or transition metal-hydroxide cathodes to thereby form amines. Preferred modes of the invention provide highly advantageous processes for producing hexamethylenediamine from adiponitrile.
