4,4′-Bipyridine (abbreviated to 4,4′-bipy or 4,4′-bpy) is an organic compound with the formula (C 5 H 4 N) 2. It is one of several isomers of bipyridine . It is a colorless solid that is soluble in organic solvents.
4,4′-Bipyridine (4,4′-bipy) is mainly used as a precursor to the N,N′-dimethyl-4,4′-bipyridinium dication commonly known as paraquat.This species is redox active, and its toxicity arises from its ability to interrupt biological electron transfer processes.
Radical dimerization of pyridine with elemental sodium or Raney nickel selectively yields 4,4'-bipyridine, [98] or 2,2'-bipyridine, [99] which are important precursor reagents in the chemical industry. One of the name reactions involving free radicals is the Minisci reaction.
2,2′-Bipyridine (bipy or bpy, pronounced / ˈ b ɪ p iː /) is an organic compound with the formula (C 5 H 4 N) 2. This colorless solid is an important isomer of the bipyridine family. It is a bidentate chelating ligand, forming complexes with many transition metals. Ruthenium and platinum complexes of bipy exhibit intense luminescence. [1]

Orellanine is a bipyridine with positively charged nitrogen atoms, and chemically resembles the bipyridine herbicides paraquat and diquat. [3] Like orellanine, paraquat and diquat are toxic not only to plants, but also to humans and livestock.
