ELEMENTAL SELENIUM REACTIONS WITH 4-PICOLINE

Abstract

A study of the reaction of the elemental selenium with 4-picoline is reported. The process was carried out at the boiling point of the 4-picoline under argon. After removing unreacted solids, the reactions products were identified by means of GC and GC-MS. The following products have been identified: 1.2-di(4-pyridyl)-ethane, 1,2-(4-pyridyl)-ethene. 4-methyl-2-(4-pyridyI)methylpyridine, 4-[2-(4-methyl)-pyridyl)]-2-(4-pyridyl)methylpyridine, 1-[2-(4-methyl)pyridyl]-l.2-di(4-pyridyl)-ethane, 1-[3-(4-methyl)-pyridyl]-l,2-di(4-pyridyl)-ethane, l-hydroseleno-1,2-di(4-pyridyl)-ethane and I-hydroperseleno-1.2-di-(4-pyridyl)-ethane.
