Neither in the solid state, nor in solution —proof of the existence of indigoid compounds such as 1 with thioxo instead of oxo groups remains elusive. The oxidation of leucoindigoid precursors does not lead to 1 in any example examined, but rather to the valence isomeric 1,2‐dithiines 2 or to macrocyclic bisdisulfides, depending on the heteroatom X (S, NCH 3 , NH, O).
