Addition Reactions of 2‐Thiazolin‐5‐thiones with Acetylenes The reaction of the 2‐thiazolin‐5‐thiones 1 and 5 , respectively, with acetylen carboxylates yields mainly 1, 4‐dithiafulvenes of type 3. In the presence of the acetylenic compounds, the 1, 4‐dithiafulvenes undergo an isomerization to give the corresponding 2, 3‐dihydrothiophene‐2‐thiones 4.
