The synthetic precursors pyridine‐2(1 H )‐thiones 2a , b and bis(pyridine‐2(1 H )‐thione) derivative 4 , using aldehydes 1a , b incorporating 2,6‐dibromophenoxy moiety, were prepared and used to synthesize the novel target materials bis[(5‐cyanopyridin‐6‐yl)sulfanyl]butanes 5a , b , bis(2‐ S ‐alkylpyridines) 8a , b , and bis(3‐aminothieno[2,3‐ b ]pyridines) 13a–c through facile procedures. Characterization of the newly prepared compounds via elemental analyses and spectral data is established.
