The compounds of the formula ##SPC1## In which R is lower alkyl, lower alkoxy or halo, x is an integer from 0 to 2, n is an integer from 0 to 3, Y is halo and R.sub.1 and R.sub.2 independently are hydrogen, lower alkyl, phenyl or substituted phenyl, or, together with the nitrogen atom, form a heterocyclic ring also containing up to one oxygen atom in the heterocycle. The compounds in which x is 0 are prepared by adding chlorine or bromine to a 1-arylthiomethanesulfonamide in the presence of pyridine to form the 1-arylthio-1, 1-dihalomethanesulfonamide. The compounds in which x is 1 or 2 is prepared by adding sodium hypochlorite or sodium hypobromite to a 1-(arylsulfinyl)methane-sulfonamide or a 1-(arylsulfonyl)methanesulfonamide to form the 1-(arylsulfinyl)-1,1-dihalomethanesulfonamide or 1-(arylsulfonyl)-1,1-dihalomethanesulfonamide, respectively. The compounds are useful as antimicrobial agents.
化学式为##SPC1##的化合物中,其中R是低烷基、低烷氧基或卤素,x是0到2的整数,n是0到3的整数,Y是卤素,R.sub.1和R.sub.2独立地为氢、低烷基、苯基或取代苯基,或者与氮原子一起形成含有一个氧原子的杂环环。当x为0时,通过在吡啶存在下将氯或溴加到1-芳基硫代甲磺酰胺中形成1-芳基硫代-1,1-二卤代甲磺酰胺来制备化合物。当x为1或2时,通过将次氯酸钠或次溴酸钠加入到1-(芳基亚磺酰基)甲磺酰胺或1-(芳基磺酰基)甲磺酰胺中形成1-(芳基亚磺酰基)-1,1-二卤代甲磺酰胺或1-(芳基磺酰基)-1,1-二卤代甲磺酰胺,分别制备化合物。这些化合物可用作抗微生物剂。
