Synthesis of organoselenium sulfonamides as new potential cytokine inducers: 2,2'-Diselenobis(benzenesulfonamides) and 1,3,2- benzothiaselenazolone 1,1-dioxides

Kloc, Krystian,Mlochowski, Jacek

, p. 67 - 71 (2007/10/03)

A convenient method for the synthesis of 2,2'- diselenobis(benzenesulfonamides) 4 and 2-substituted 1,3,2- benzothiaselenazole 1,1-dioxides 2, has been elaborated. It is based on the conversion of 2-aminobenzenesulfonic acid into bis[2-(chlorosulfonyl)phe
