A process is described for the preparation of an N-alkyl- or N,N-dialkyl-1,2-diaminoethane of the general formula I STR1 where R1 is hydrogen or methyl, R2 is C1 - to C5 -alkyl, and R3 is hydrogen or C1 - to C5 -alkyl, with the proviso that the total number of carbon atoms in R2 and R3 is an integer from 1 to 6, by reacting an imine of the general formula II STR2 with an amine of the general formula III STR3 where R1, R2 and R3 are as defined above, which comprises carrying out the reaction in the presence of carbon dioxide at from 10° to 150° C. and at from 0.5 to 50 bar.

The crystal structures of , , >, and have been determined.They are all very similar, with the hydrazido- (or hydroxylaminato-) residue bound side-on and asymmetrically in the usual way, and an N-N (or N-O) separation indicating a single bond.Some related dithiocarbamato-derivatives have also been characterized.
