Previously unknown mono-, di- and in some cases tri- and tetra- carbocycle-substituted quinoxalines (2–8), 2,1,3-benzothiadiazoles (11, 12, 14–17) and 2,1,3-benzoselenadiazoles (20-25) were synthesized by nucleophilic substitution of fluorine in 5,6,7,8-t

The use of the phthalimido group as the leaving group makes it possible to obtain asymmetric 1,7-diaryl-1,3,5,7-tetraaza-2,4,6-trithia-1,2,5,6-heptatetraenes, which are not obtainable by the previously known methods.Cesium fluoride in acetonitrile increases the nucleophilicity of the nitrogen atom of the N-trimethylsilyl derivatives of acyclic azathienes and phthalimide.In acetonitrile solution a spontaneous shortening of the sulfur-nitrogen chain of 1,7-bis(trimethylsilyl)-1,3,5,7-tetraaza-2,4,6-trithia-1,2,5,6-heptatetraene takes place.
