Reactions of 2,4,6-tripyridyl-1,3,5-s-triazine and its Fe(II) complex with OH° and eaq-

Pulse radiolysis studies indicated that OH· and eaq- formed adducts with 2,4,6-tripyridyl-1,3,5-s-triazine (tptz). The OH-adduct showed an absorption maximum at 290 nm, while the adduct formed from the attack of eaq- and subsequent protonation of the anion, has an absorption maximum at 300 nm. In case of the complex, Fe(tptz)22+, both OH· and eaq- gave ligand centered adducts. All the adducts decayed by second order dimerization or disproportionation, a disproportionation reaction in case of the complex.
