A new three‐component strategy from aldehyde, p ‐toluenesulfonyl hydrazide and potassium thiocyanate for the synthesis of 2‐aminothiadiazoles promoted by I 2 under metal‐free conditions has been described. Potassium thiocyanate was used as an odorless and low‐toxicity sulfur source. A wide range of aromatic aldehydes can smoothly undergo the three‐component cyclization reaction under the optimized conditions to give the corresponding products in moderate to good yields.
