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

In contrast to thermolysis of 1,3λ4δ2,2, 4-benzodithiadiazine (1) and its 5,6,7,8-tetrafluoro derivative 2 in dilute (10-3 M) hydrocarbon solutions, which leads to persistent 1,2,3-benzodithiazolyls in nearly quantitative

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.
CYCLIC ARYLENEAZACHALCOGENENES PART III. SYNTHESIS OF POLYFLUORINATED 2,1,3-BENZOTHIA(SELENA)DIAZOLES

1-(4-X-Tetrafluorophenyl)-3-trimethylsilyl-1,3-diaza-2-thiaallenes (X= H, CH3, Br, F, CF3) treated with CsF in acetonitrile or THF cyclized to 6-X-4,5,7-trifluoro-2,1,3-benzothiadiazoles whose reduction led to the corresponding 1,2-diaminobenzenes.Cyclization of the latter with SeCl4 gave 6-X-4,5,7-trifluoro-2,1,3-benzoselenadiazoles.
