A compound of general formula (I), wherein A represents a group of general formula (a) or (b) in which the or each X independently represents a halogen atom or an optionally substituted alkyl, alkoxy, aryl or aryloxy group, or an alkenyloxy, alkynyloxy, alkylthio, haloalkylthio, alkenylthio, alkynylthio, alkylsulphinyl, alkylsulphonyl or cyano group; and n is 0, an integer from 1 to 4, or, for the phenyl group, 5; or A represents a group of general formula (c) in which each of R<4>, R<5> and R<6> independently represents a hydrogen or halogen atom, an optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, aryl, aralkyl, alkaryl, alkoxy, amino, mono- or di-alkylamino, alkoxycarbonylamino, arylamino, dialkylcarbamoyl, acyl or acylamido group or a cyano group, with the proviso that R<5> and R<6> do not represent an acyl, acylamido or cyano group; Z represents an oxygen or sulphur atom; R<1> and R<2> each independently represents a hydrogen atom or an optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, heterocyclyl, aryl, aralkyl, alkaryl, hydroxy, alkoxy, alkenyloxy, alkynyloxy, alkylcarbonyl, alkoxycarbonyl, amino, mono- or di-alkylamino, alkoxycarbonylamino, arylamino, arylalkylamino or dialkylcarbamoyl group, or together represent an alkylene chain which is optionally interrupted by an oxygen or sulphur atom or by a group -NR- in which R represents a hydrogen atom or an alkyl group; and Q<1>, Q<2> and Q<3> each represents a nitrogen atom or a group CR<3> in which R<3> represents a hydrogen atom or an optionally substituted alkyl, alkoxy, alkylthio or mono- or di-alkylamino group, provided that all three of Q<1>, Q<2> and Q<3> are not a nitrogen atom or the group CR<3>. |
