Ferroin Chelation Group

Name:
Ferroin Chelation Group
Detailed information:
A functional group characteristic of heterocyclic ring nitrogen compounds:

Among such compounds are 2,2′-bipyridine; 1,10-phenanthroline; and the 2-pyridyl triazines. These provide a large number of terminal (C—H) groups in which the hydrogen can be replaced by many chemical groupings (carboxyl, hydroxyl, halogen, etc.). Thus, synthesis of an almost endless number of substituted ferroin reactants is possible. About 200 such chelation reagents have been synthesized. Ferroin chelation chemicals in general form complex undissociated cations with divalent metal ions, e.g., [(C₁₂H₈N₂)₃Fe]²⁺.
