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.
