Herbicidally active compounds of the formula <IMAGE> in which 1 represents a hydrogen or chlorine atom, R2 represents a hydrogen atom, a cyano group, an optionally substituted radical selected from alkyl, aryl, alkanoyl, benzoyl, alkoxycarbonyl, alkenoxycarbonyl, alkinoxycarbonyl, aralkoxycarbonyl and aryloxycarbonyl, or a radical of the general formula -COOM, in which M represents a hydrogen atom, one equivalent of an alkali metal ion or alkaline earth metal ion or optionally substituted ammonium, and R3 represents a cyano group or a radical of the general formula <IMAGE> wherein Y represent an oxygen or sulphur atom or an imino (NH) or alkylimino (Nalkyl) group, R4 and R5 independently of each other represent a hydrogen atom or a methyl group, n is 0 or 1 and Z represents an optionally substituted radical. Novel intermediates therefor are also shown.
