Compounds of the formula <IMAGE> (I) and a process for their preparation by reacting azabutadienes with dienes, especially 1,3-butadiene, in the presence of catalysts are described. In the formula I, R1 and R3 independently of one another are hydrogen or alkyl having 1-8 C atoms and R2 and R4 independently of one another are alkyl having 1-8 C atoms, or R1 and R2 and/or R3 and R4 together with the bonding C atom form a cycloaliphatic ring having 4-8 C atoms, and R5 and R6 independently of one another are hydrogen or alkyl having 1-4 C atoms. The compounds of the formula I are valuable intermediates for the preparation of active compounds for combating plant pests.
