Bipyridines are a family of organic compounds with the formula (C 5 H 4 N) 2, consisting of two pyridyl (C 5 H 4 N) rings. Pyridine is an aromatic nitrogen-containing heterocycle. The bipyridines are all colourless solids, which are soluble in organic solvents and slightly soluble in water. Bipyridines, especially the 4,4' isomer, are mainly of ...

Unsymmetrically substituted 2,2'-bipyridines can be prepared by cross coupling reaction of 2-pyridyl and substituted pyridyl reagents. [4] Structure
4,4′-Bipyridine was first obtained in 1868 by the Scottish chemist Thomas Anderson via heating pyridine with sodium metal. [1] However, Anderson's empirical formula for 4,4′-bipyridine was incorrect. [2]
The bis-triazinyl bipyridines (BTBPs) are a class of chemical compounds which are tetradentate ligands similar in shape to quaterpyridine. The BTBPs are made by the reaction of hydrazine and a 1,2-diketone (such as hexane-3,4-dione ) with 6,6'-di cyano -2,2'-bipyridine.

Quaterpyridine refers to a family of pyridine derivatives with the formula (NC 5 H 4-C 5 H 3 N) 2.These compounds can also be viewed as bipyridine decorated with two pyridyl substituents.
