Compounds of the formula ##STR1## 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, R.sub.1 and R.sub.3 independently of one another are hydrogen or alkyl having 1-8 C atoms and R.sub.2 and R.sub.4 independently of one another are alkyl having 1-8 C atoms, or R.sub.1 and R.sub.2 and/or R.sub.3 and R.sub.4 together with the bonding C atom form a cycloaliphatic ring having 4-8 C atoms, and R.sub.5 and R.sub.6 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.
