## Abstract An effective synthesis of 3‐benzoyl‐2(1 __H__)‐pyridinethiones **5a** – **n** from stable enol salts **4** of pentene‐1,5‐diones and isothiocyanates is described. An attempt to prepare a 3‐acetyl‐2(1 __H__)‐pyridinethione from the cyano compound **7** and CH~3~MgX yielded the ketimine *
