Synthesis and Oxidative Cleavage of Poly(Trimethylene Diselenides)

摘要

1-Bromo-3-chloropropane and elemental selenium react in hydrazine hydrate-alkali and hydra-zine 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.
