Fused 1,2,4-thiadiazoles (14-18 and 26-31) are conveniently prepared by reacting the chlorothiadiazolone 12 with omega-aminonitriles and aminoazoles. During these reactions the original thiadiazole ring is opened and a new, fused thiadiazole rig is formed, probably via a hypervalent sulfur intermediate. The products derived from the aminoazoles were analyzed by X-ray crystallography and found to have structures different from those published earlier.(7)
