Abstract Ladder oligophenothiazines were synthesized by direct catalyzed insertion of elemental sulfur in anilino‐substituted phenothiazines and para ‐oligoanilines. The starting 3‐ and 3,7‐anilino derivatives of phenothiazine were prepared with improved selectivities and yields by new syntheses. The oxidability of the oligomers is discussed.
