3,5-Dibromopyridine Usage And Synthesis
Chemical PropertiesLight-Yellow Solid
Uses3-Acetylamino-5-ethoxypyridine was prepared by converting 3, 5-dibromopyridine with sodium ethylate into 3-bromo-5-ethoxypyridine, allowing this substance to interact with ammonia and acetylating the aminoethoxypyridine thus formed with acetic anhydride. Lithiation of 3, 5-dibromopyridine with LDA and subsequent reaction with electrophiles provided 4-alkyl-3, 5-dibromopyridines 2 in high yield. Ligand was prepared by a Pd(0)-catalyzed cross-coupling reaction of 3,5-dibromopyridine and 5-tributylstannyl-3,3?-bipyridine. The synthesis of 3, 5-bis (2-indolyl) pyridine and 3-[(2-indolyl)-5-phenyl] pyridine derivatives as includes Stille or Suzuki type reactions, which were realized on the 3,5-dibromopyridine.
DefinitionChEBI: 3,5-dibromopyridine is a dibromopyridine.
General Description3,5-Dibromopyridine undergoes lithiation with lithium diisopropylamide and on subsequent reaction with electrophiles yields 4-alkyl-3,5-dibromopyridines.
