Preparation of α,β-diaminoacrylonitriles

α,β-Diaminoacrylonitriles of the general formula I where R1, R2 and R3 are identical or different and independently of one another are each hydrogen, alkyl, cycloalkyl, aralkyl, aryl or a heterocyclic radical, and the organic radicals R2 may furthermore be bonded to one another to form a 6-membered or 7-membered ring, or R2 and R3 may be bonded to one another to form a 5-membered or 6-membered ring, are prepared by reacting an α-dicarbonyl compound R1 COCHO, or a reactive derivative of this with (a) a salt of sulfurous acid or sulfur dioxide, (b) an amine HNR2 R3 or an aliphatic diamine R3 HN-(CH2)n NHR3 where n is 2 or 3 and (c) hydrocyanic acid or a hydrocyanic acid donor in any sequence.
