## 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 *
In the title structure, C 16 H 10 N 2 O 3 S, there are two crystallographically independent molecules in the asymmetric unit. In one molecule, the dihedral angle between the indole ring system and the phenyl ring is 68.3 (2) , and in the other it is 80.3 (2) . C-HÁ Á ÁO, C-HÁ Á ÁN and C-HÁ Á Á inter
