Two Sulfonamido Sulfonyls Having No Sulfonamido Nitrogen Between The Sulfonyls Patents (Class 564/83)
  • Phenoxiodinin-5-ium antimicrobial compounds
    Patent number: 4440943
    Abstract: 3,7-Substituted phenoxiodinin-5-ium compounds are effective against a variety of aerobic and anaerobic bacteria as well as fungi. The compounds of this invention may be prepared by the direct iodination of a suitably substituted diphenyl ether with iodosyl sulfate in concentrated sulfuric acid. The resulting bisulfate anion may be exchanged with a desired anion by standard metathetic processes.
