Cpds. of formula (I) (where R1 is alkyl, alkoxy, alkylthio, alkoxyalkylthio, NH2 or mono- or dialkylamino, R2 is alkoxy, alkylthio, NH2 or mono- or dialkylamino, R3 is opt. substd. phenyl, Y is H, Cl or Br, n is 0 or 1, and X is O or S), e.g. (I; n = 1, R1=R2 =OEt, R3 = p-Cl-C6H4, X = S Y = H) are new cpds. which may be prepd. by reacting a halide of formula (II) (where Hal is F,Cl Br or I) with a cpd. of formula (III) (where M is H or monovalent metal), the reaction being carried out in the presence of an acid binding agent when M is H. (I) have broad biocidal activity, but are partic. useful as insecticides and acaricides. Some cpds. (I) are also active against phytopathogenic nematodes.
