Abstract

Compounds of the formula I are crop protection agents, in particular fungicides and herbicides. They are prepared by reacting compounds of the formula III in the presence of a halogen or compounds of the formula II as such with a base which corresponds to the radical Y. If R<3> denotes hydrogen, the resulting compound I can be N-alkylated. <IMAGE>
