The new halogenated sulphides of the formula ##STR1## in which R.sup.1 to R.sup.8 are identical or different and denote hydrogen or halogen, at least one of the radicals R.sup.1 to R.sup.8 representing halogen, and wherein R.sup.1 and R.sup.2, and/or R.sup.3 and R.sup.4 can optionally form an olefinic bond, and A and B are identical or different and denote nitrile, carboxyl, carboxylate or carboxamide, can be prepared by halogenation of bis-(cyanoethyl) sulphide, or by splitting off hydrogen halide from a halogenated bis-(cyanoethyl) sulphide, or by reacting 3-halogeno-acrylonitriles with sulphides. The new compounds can be active compounds in microbicidal agents.
新的卤代硫化物的化学式为##STR1##其中R.sup.1至R.sup.8相同或不同,表示氢或卤素,至少一个基团R.sup.1至R.sup.8代表卤素,其中R.sup.1和R.sup.2,和/或R.sup.3和R.sup.4可以选择性地形成烯烃键,A和B相同或不同,表示腈、羧基、羧酸盐或羧酰胺,可以通过卤代双(氰乙基)硫化物的卤代反应制备,或者通过从卤代双(氰乙基)硫化物中脱去氢卤化物,或通过3-卤代丙烯腈与硫化物反应制备。这些新化合物可以作为微生物杀灭剂中的活性成分。
