N-(5,7-Dibromo-1,3-benzoxathiol-2-ylidene)-N-methylmethanaminium bromide and the analogous diodo iodide, new compounds, are prepared by the thermal rearrangement of O-(2,4,6-tribromophenyl)-N,N-dimethylthiocarbamate and O-(2,4,6-triiodophenyl)-N,N-dimethylthiocarbamate. The first-named compound has antimicrobial utility. Both compounds are useful as starting materials for the preparation of bis-(3,5-dibromo-2-hydroxyphenyl)disulfide and 2,4-diiodo-6-mercaptophenol, respectively, by hydrolysis of the two first-named compounds with methanolic sodium hydroxide. Both the disulfide and the mercaptophenol compounds have antimicrobial utility.
N-(5,7-二溴-1,3-苯并噻吩-2-亚基)-N-甲基甲烷胺溴化物和类似的二碘化物是通过O-(2,4,6-三溴苯基)-N,N-二甲基硫代氨基甲酸酯和O-(2,4,6-三碘苯基)-N,N-二甲基硫代氨基甲酸酯的热重排制备的。第一个化合物具有抗微生物作用。这两种化合物都可用作制备双-(3,5-二溴-2-羟基苯基)二硫化物和2,4-二碘-6-巯基苯酚的起始物质,通过与甲醇钠氢氧化物水解两个第一命名化合物。二硫化物和巯基苯酚化合物都具有抗微生物作用。
