1-Chloro-1,4-diaryl-2,3-diazabutadienes (Ar1CCl=NN=CHAr2), prepared by the reaction of thionyl chloride with aroylhydrazones (Ar1CONHN=CHAr2), react with thiosemicarbazide or thiocarbohydrazide to give 2-arylidenehydrazino-5-aryl-1,3,4-thiadiazoles, and with potassium thiocyanate to give 1-thiocyanato-1,4-diaryl-2,3-diazabutadienes which isomerize thermally to arylideneamino-5-aryl-1,3,4-thiadiazoles. 1-Chloro-1,4-diphenyl-2,3-diazabutadiene reacts with potassium ethylxanthate to give a 1-ethylxanthyl-2,3-diazabutadiene which on pyrolysis yields 2,5-diphenyl-1,3,4-thiadiazole.
The Mechanism of Cyclization of 1,4-Diaryl-1-azido-2,3-diazabuta-1,3-dienes to Tetrazoles. Imidoyl Azides stabilized by Slow Nitrogen Inversion

, p. 535 - 540 (2007/10/02)
The imidoyl azides (9) are stabilized in the open chain azido form because of their configuration (which is Z about the C=N bond) and slow ZE isomerization.The rates of conversion of the azides (9) into the isomeric tetrazoles (12) have been measused and
