CA 2206125

Compounds of the formula (I) or salts thereof are suitable as herbicides and plant growth regulators. The compounds (I) are prepared by processes analogous to known processes, in some cases via novel intermediates of the formula (II) R5 represents H, halogen atoms, NO2, CN or optionally halogen substituted (C1-C4)alkyl, alkoxy, alkylcarbonyl or alkoxycarbonyl; R6 represents H or (C1-C4)alkyl; Q represents 0 or NR*; W represents O or S; Z represents CH or N; X and Y represent H, halogen atoms or optionally substituted (C1-C4) alkyl, alkoxy or alkylthio; and R11 to R4 represent H or a range of organic radicals.

Composés de formule (I) ou leurs sels, formule dans laquelle R<1> à R<6>, W, Q, X, Y et Z sont tels que définis dans la formule (I) de la revendication 1, utilisés comme herbicides et régulateurs de croissance végétale. La fabrication des composés (I) s'effectue suivant des procédés analogues à des procédés connus (voir revendication 5), impliquant, en partie, l'utilisation de produits intermédiaires nouveaux de formule (II).
