Bis(2-chlorosulfonylphenyl) diselenide - the substrate for organoselenium sulfonamides
Kloc, Krystian,Mlochowski, Jacek,Mhizha, Sungano
, p. 4049 - 4057 (1997)
Synthesis of bis(2-chlorosulfonylphenyl) diselenide (11) from 2-amino-benzenesulfonic acid was elaborated. It was shown that (11) is a good starting material for synthesis of the organoselenium sulfonamides, such as bis(2-sulfamoylphenyl) diselenides (3)
