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.

机译:Cpds。式(I)的化合物(其中R 1是烷基,烷氧基,烷硫基,烷氧基烷硫基,NH 2或单或二烷氨基,R 2是烷氧基,烷硫基,NH 2或一或二烷氨基,R 3是优选取代苯基,Y是H,Cl或Br,n为0或1,X为O或S),例如(I; n = 1,R1 = R2 = OEt,R3 = p-Cl-C6H4,X = S Y = H)是新的cpds。可能需要准备。通过使式(II)的卤化物(其中Hal为F,Cl Br或I)与cpd反应。式(III)的式(III)(其中M是H或一价金属),当M是H时,该反应在酸结合剂的存在下进行。(I)具有广泛的杀生物活性,但是是部分杀生物剂。可用作杀虫剂和杀螨剂。一些cpds。 (I)对植物病原线虫也有活性。
