ABSTRACT:
There are described compounds of the formula ##STR1## wherein R.sub.1 and R.sub.2 independently of one another represent alkyl having 1-8 C atoms, or together with the bond C atom they represent a cycloaliphatic ring having 4-8 C atoms, and R.sub.3 represents ethyl; or wherein R.sub.1 represents alkyl having 1-8 C atoms, R.sub.2 represents hydrogen, or alkyl having 1-8 C atoms, and R.sub.3 represents tertiary alkyl having 4-8 C atoms.
The compounds of the formula I can be produced in a simple manner, in good to very good yields, by isomerisation of suitably substituted allylamines in an inert organic solvent and in the presence of a catalyst. The compounds of the formula I constitute valuable intermediates for producing active substances for combating plant pests.
