✦ Synopsis


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.
