oroftheformula:
wherein R1, R2 and R', which may be the same or different, each represent hydrogen, phenyl, alkyl of 1 to 6 carbon atoms, or alkenyl or alkynyl of 3 to 6 carbon atoms, each of which may be unsubstituted or substituted by one or more halogen atoms, hydroxy groups, cyano groups, carboxy groups, alkoxycarbonyl groups of 2 to 5 carbon atoms or alkoxy groups of 1 to 4 carbon atoms; or R' and R' together represent a single bond; Hal represents fluorine, chlorine, bromine or iodine; and R3 represents 2-iodophenyl, 2,5-dihalophenyl, 2-methylthiophenyl, cyclohexyl, cyclohexylalkyl, cyclohexenyl, cyclohexadienyl, 1-naphthyl, 2-naphthyl or biphenylyl, each of the cyclohexyl, cyclohexenyl, cyclohexadienyl, naphthyl or biphenylyl moieties of which may be unsubstituted to substituted by one or more alkyl, alkoxy or alkylthio groups of 1 to 6 carbon atoms, hydroxy, mercapto or cyano groups, halogen atoms, alkanoyloxy groups of 2 to 6 carbon atoms, amino or phenylamino groups, or alkylamino or dialkylamino groups, each alkyl moiety of which is of 1 to 6 carbon atoms, are effective to combat pests, particularly acarids and their eggs.
The compounds are new and processes for their preparation are described.
