Abstract A study of the reaction of the elemental sulfur with 3-picoline is reported. The process was carried out at the boiling point of the 3-picoline under argon. After removing unreacted solids, the reaction products were identified by means of LC, GC and GC-MS. The following products have been identified: 1, 2di-(3-pyridyl)-ethane, Z-1, 2-di (3-pyridyl)- ethene, E-1, 2-di (pyridyl)-ethene, 6-(3-pyridyl)-thieno [2, 3b] pyridine, 4, 5-di (3-pyridyl)- ...
