eryl)‐1,3,4‐thiadiazoles, and some of their salts were prepared and studied by multinuclear 1H, 13C, 15N, 19F and 2D NMR spectroscopy. The acetylation of thiosemicarbazones is accompanied by ring closure to form the corresponding 1,3,4‐thiadiazolines and 1,3,4‐thiadiazoles. 15N NMR spectroscopy is a unique method for the identification of thiadiazole pyridinium salts.
