Resumo
The reactions of 4-(2-bromophenyl)-1,2,3-thia-and -selenadiazoles with amines in the presence of potassium carbonate and copper(I) iodide afforded 2-aminobenzo[b]chalcogenophenes. The corresponding thiaand selenamides, prepared by interaction of 4-(2-bromophenyl)-1,2,3-thia- and -selenadiazoles with amines in the absence of copper salt, were transformed into 2-aminobenzo[b]chalcogenophenes by the action of potassium carbonate and copper(I) iodide in DMF in different yields.
