Syntheses in the benzo[2,1,3]thiadiazole series

I. New sulfo derivatives of benzo[2,1,3]thiadiazole
  • F. S. Mikhailitsyn


The synthesis of the previously unknown 7-bromobenzo[2,1–3]thiadiazole-4-sulfonic acid, its acid chloride and amides, and the corresponding sulfinic acid, which was subsequently converted to the ethylsulfonyl derivative, is described. It is shown that the bromine in amides of 7-bromobenzo[2,1,3]thiadiazole-4-sulfonic acid and the corresponding 4-ethylsuifonyl derivative is readily replaced by an amine.
