The reactions of 2-(bromoseleno)benzenesulfonyl chloride with primary amines toward 2,2′-diselenobis(benzenesulfonamides) and 1,3,2-benzothiaselenazole 1,1-dioxides:: New oxygen-transfer agents, antimicrobials and virucides

The reaction of title compound 6 with primary aliphatic or aromatic amines was investigated. The products were 2,2'-diselenobis(benzenesulfonamides) (4) accompanied in some cases by 1,3,2-benzothiaselenazole 1, 1-dioxides (3). Exceptionally, when aniline was a reagent, 2-(sulfamoylphenyl)phenylselenenylanilide was produced. These results are interpreted in the light of the proposed mechanisms. The compounds 3 and 4 exhibited catalytic activity in hydroperoxide oxidation of cyclohexanone (12) and 1-naphthaldehyde N,N-dimethylhydrazone (17). Although they were inactive against patogenic bacteria and fungi an appreciable antiviral activity against HSV-1 and EMCV of the compounds 3b, 3c and 4b was observed.
