One-pot synthesis of azobenzene derivatives by oxidation of 2,3-dihydrobenzothiadiazines

Cannazza, Giuseppe,Perrone, Serena,Rosato, Francesca,D'Accolti, Lucia,Parenti, Carlo,Troisi, Luigino

, p. 962 - 966 (2014)

An oxidative route to N-substituted sulfonamidic azobenzene derivatives is reported. A mechanism, based on a rationalization of previous findings, is proposed. This simple one-pot method could be adapted to the synthesis of a range of substituted sulfonylazobenzenes with potential applications in the pharmaceutical and industrial fields.
