Kinetics of reaction of tris[5,5′ {3-(2-pyridyl)-1,2,4, triazine-5,6 diyl} bis-2-furansulphonic acid]iron(II) with hydroxide ion

Summary The kinetics of dissociation of the iron(II) tris complex of ferene, 5,5{3-(2-pyridyl)-1,2,4-triazine-5,6-diyl}] bis-2-furansulphonic acid in aqueous basic and acidic media have been studied spectrophotometrically at 298.2K. Rate constants at several hydroxide ion concentrations are reported for both steps observed in basic solution. A possible dissociation mechanism is presented and the comparative reactivity of this complex with other iron(II)-diimine complexes is assessed.Presented in part at the 191st Am. Chem. Soc. Nat.
