ABSTRACT Compounds of the general formula Image (I) wherein each of R1 and R2 independently represents a hydrogen atom or an optionally substituted alkyl, cycloalkyl or aryl group, or R1 and R2 together represent an optionally substituted alkylene group; each of X and Y independently represents one of the groups CH6R7, C-O, C=N-Z, CH-NH2, Image or Image in which n is 2 or 3; R6 represents a hydrogen atom, an optionally substituted alkyl or aryl group or a group Or formula -OA in which A represents a hydrogen atom, a heterocyclyl group, an acyl group derived from a carboxylic or a substituted carbamic acid, or a group CR10R11R12; R7 represents a hydrogen atom or an optionally substituted alkyl or aryl group; Z represents a hydroxy, alkoxy, acyloxy, amino, alkylamino or dialkylamino group; R3 represents a hydrogen atom or an optionally substituted alkyl group; each of R4 and R5 independently represents a hydrogen atom or an optionally substituted alkyl group; each of R8 and R9 independently represents a hydrogen atom, an alkyl group or an aryl group; each of R10 and R11 independently represents a hydrogen atom or an alkyl group; R12 represents an alkoxyalkoxy group, a heterocyclyl group, an alkoxycarbonyl group, an optionally substituted aryl group, an alkylthio group or a substituted carboxamido group; and Ar represents an optionally substituted fully unsaturated ring having 5 or 6 atoms in the ring of which one is a nitrogen atom and the remainder are carbon atoms, or the N-oxide or an acid addition salt thereof, or Ar represents an optionally substituted phenyl group; with the proviso that if both X and Y represent groups CR6R7, at least one substituent R6 is a group -OA; exhibit useful herbi- cidal activity.
