High Yield Synthesis of 5,5′-Dimethyl-2,2′-bipyridine and 5,5″-Dimethyl-2,2′:6′,2″-terpyridine and Some Bisfunctionalization Reactions Using N-Bromosuccinimide

All articles of this category 5,5′-Dimethyl-2,2′-bipyridine and 5,5″-dimethyl-2,2′:6′,2″-terpyridine were synthesized in multigram quantities in high yields utilizing organotin intermediates and Stille coupling procedures. The obtained ligands were dibrominated using N -bromosuccinimide. 2,2′-bipyridines - 2,2′:6′,2″-terpyridines - Stille coupling - organotin intermediates - radical bromination
