Electron Transfer Reactions of RuIII(edta) Containing the N-Heterocyclic Ligand Pyrazine: Kinetic and Mechanistic Studies

RuIII(edta) complexes as molecular redox catalysts in chemical and electrochemical reduction of dioxygen and hydrogen peroxide: inner-sphere versus outer-sphere mechanism

“…The [Ru III (edta)(pz)] − complex can easily be reduced electrochemically ( E 1/2 value corresponding to the [Ru III (edta)(pz)] − /[Ru II (edta)(pz)] 2− couple is 0.252 V vs. SHE) 19 or chemically (in the presence of reducing agents viz. ascorbic acid) 22 to its ruthenium( ii ) analogue, [Ru II (edta)(pz)] 2− ( Fig. 1 ).…”

Prospect of Ru(edta) complexes in nitrogen cycle electrocatalysis: a mini review

“…21,22 While studying electron transfer reactions of [Ru III (edta) ( pz)] − with different electron donors, viz. ascorbic acid, catechol, sulfite, thiols, and bisulfide, 49 we noticed that the addition of hydrazine to the pale-yellow solution of [Ru III (edta) ( pz)] − resulted in spectral changes (shown in Fig. 3) consistent with the formation of the [Ru II (edta)( pz)] 2− complex (λ max at 465 nm), confirming the ability of hydrazine (N 2 H 4 ) to reduce [Ru III (edta)( pz)] − to [Ru II (edta)( pz)] 2− (eqn ( 18)).…”
