Reaction of 2‐methyl‐3‐thiocyanatocrotonaldehyde with aniline hydrochloride and subsequent addition of dicyclohexylamine afforded a new 6a‐thia(S IV )‐1,6‐diazapentalene. The presence of the NSN bond was verified through the N 1s and S 2p binding energies and the nitrogen‐nitrogen coupling constant in the doubly 15 N‐labelled compound, prepared by using [ 15 N]aniline hydrochloride.
