Synthesis and oxidative cleavage of poly(trimethylene diselenides)

Abstract

1-Bromo-3-chloropropane and elemental selenium react in hydrazine hydrate-alkali and hydrazine hydrate-amine systems to form poly(trimethylene diselenides). The reductive cleavage of the resulting selenokols yielded 1,3-propanediselenol, 1,2-diselenolane, and bis(alkylseleno)propanes. These compounds are important reagents for organic synthesis and ligands for complex formation. The products obtained were studided by GC-MS.
