Novel compounds, i.e. 3,5-bis(chloromethylthio)-4-cyanoisothiazole; 2,5-bis(chloromethylthio)-1,3,4-thiadiazole; and 3,5-bis(chloromethylthio)-1,2,4-thiadiazole are prepared by reacting an alkali metal aryl mercaptide with bromochloromethane in the presence of a quaternary ammonium salt. These novel compounds have microbiological activity and are also useful as intermediates in the preparation of the corresponding thiocyanomethylthio compounds which have antimicrobial activity.
新的化合物,即3,5-双(氯甲硫基)-4-氰基异噻唑;2,5-双(氯甲硫基)-1,3,4-噻二唑;以及3,5-双(氯甲硫基)-1,2,4-噻二唑是通过在季铵盐存在下,将碱金属芳基硫醇与溴氯甲烷反应制备而成。这些新的化合物具有微生物活性,并且还可用作制备相应的硫氰甲硫基化合物的中间体,这些化合物具有抗微生物活性。
