In contrast to a known procedure for the synthesis of 1,2,4-thiadiazoles 3 from N-unsubstituted N'-chlorobenzamidines 1a and potassium S-methyl cyanimidodithiocarbonate (2) the substituted amidines 1b - 1e form thiadiazoles 5a - d containing both nitrogen atoms of amidines in the ring system. Key Words: N-Chloroamidine / Thiadiazoles
