A new improved synthesis and X‐ray crystal structure of [1,4]dithiino[2,3‐<i>b</i>]‐1,4‐dithiin

Abstract

Abstract [1,4]Dithiino[2,3‐ b ]‐1,4‐Dithiin ( 3 ) has been synthesised in high yield by a one‐step procedure starting with sodium 1,3‐dithiole‐2‐thione‐4,5‐dithiolate ( 2 ). The X‐ray crystal structure shows non‐planarity of the fused ring system as well as short intermolecular S ⃜S contacts.
