Abstract: The level of an unsaturated cyclic imine (I) of the formula (I)where R1 is alkenyl having 3, 4, 5, 6, 7, 8, 9, 10, 11 carbon atoms belonging to the ring system, in a mixture comprising hexamethylenediamine and an imine (I) is reduced by electrochemical conversion of an imine (I) in a mixture comprising hexamethylenediamine and an imine (I) in the presence of solvated protons into a saturated cyclic amine of the formula (II)

Abstract: THE LEVEL OF AN UNSATURATED CYCLIC IMINE (?) OF THE FORMULA (?) R1 (CH)=N (?) WHEREI R1 IS ALKENYL HAVING 3,4,5,6,7,8,9,10,11 CARBON ATOMS BELONGING TO THE RING SYSTEM,IN A MIXTURE COMPRISING HEXAMETHYLENEDIAMINE AND AN IMINE (?) IS REDUCED BY ELECTROCHEMICAL CONVERSION OF AN IMINE (?) IN A MIXTURE COMPRISING HEXAMETYLENEDIAMINE AND AN IMINE (?) IN THE PRESENCE OF SOLVATED PROTONS INTO A SATURATED CYCLIC AMINE OF THE FORMULA (??)R1 (CR?H) -N-H (??).
