General description

2,2′-Bipyridyl also known as 2,2′-bipyridine, is a symmetrical bipyridine commonly used as a neutral ligand for chelating with metal ions. It is a bidentate ligand which has been employed transition metal catalysis, aluminum initiated polymerization, and various other inorganic syntheses. This compound adheres to the principles of greener chemistry, ensuring catalytic efficiency. Click here for more information

Application

2,2′-Bipyridyl has been used in:
  • the preparation of fluorescent dyes like products 754730, 544981, 804215.
  • the preparation ofcopper(II)-bipyridine-naringenin complex.
  • the preparation of 2,2′-bipyridyl hydrobromide.
  • as a ligand in the greener oxidation of alcohols under aerobic conditions
  • as a complex with CuBR2 in the green synthesis of propargylamines
  • the synthesis of [Ru(bipy)3]Cl2, a common metal complex with usefulphotochemistry often used in photoredox catalysis as a sensitizer
