N-(2-bromotetrafluoroethyl) derivatives of five-membered nitrogen-containing heterocycles

The synthesis of N-(2-bromotetrafluoroethyl) derivatives of five-membered heterocycles containing one to three nitrogen atom(s) in the ring has been carried out. The reactions of these compounds with various sulfur-containing nucleophiles have been studied, and corresponding sulfides, sulfones and sulfinic acid salts were obtained.
