Abstract 2H-1-benzothiete (1) and 2H,5H-benzo[1,2-b:4,5-b′]bisthiete (3) react in form of their open valence isomers with the trithiocarbonic acid esters 2a–c. The one- or twofold cycloaddition reactions yield 1,3-dithiin rings, in which C-2 is a spiro-C atom, that bears four sulfur groups. The bifunctional reactant 3 gives additionally band-shaped, hardly soluble oligomers.
