ABSTRACT:
A process for the preparation of tetrasubstituted novel compounds of the formula ##STR1## wherein Y' is selected from the group consisting of --CN and --COOR, R is alkyl of 1 to 6 carbon atoms and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are individually selected from alkyl of 1 to 4 carbon atoms or R.sub.1 and R.sub.2 or R.sub.3 and R.sub.4 together with the carbon atoms to which they are attached form a carbon homocycle of 3 to 6 carbon atoms with the 2 substituents not forming the ring being alkyl of 1 to 4 carbon atoms or R.sub.1 and R.sub.2 on the one hand and R.sub.3 and R.sub.4 on the other together with the carbon atom to which they are attached form a carbon homocycle of 3 to 6 carbon atoms and Z is an aromatic group which are useful intermediates for the preparation of insecticidal esters.
