Tetraaza ruthenium complexes

Tetraaza ruthenium complexes, d5/tran5-[Ru(N)4LL ]" with N = NH3 or 12- to 16-memberedtetraazamacrocycle (Figure 2), are highly stable and can serve as a model to rmderstand thermodynamic control and photochemical reactions. In the presence of NO or N02 in acidic medium, a ds/[Pg.268]

A range of low spin, octahedral ruthenium(III) complexes incorporating tetraaza macrocyclic ligands have been synthesized. Reaction of [RuClsi OHj)] with L in alcoholic solvent under reflux affords trani-[RuCl2(L)] (L = Oxidative dehydrogenation of the coor-... 

The kinetic data for a series of outer-sphere electron transfer reactions between the [Rh2(02CCH3)4(CH3CN)2] couple and nickel tetraaza macrocycles and iron and ruthenium tris(polypyridine) complexes in acetonitrile have been correlated in terms of the Marcus relationship, yielding a [Rh2] electron exchange rate constant of 3.0 1.7 x 10 M A somewhat smaller value of 5.3 1.3 x... 

Clay-modified electrodes with ruthenium purple Enzymic treatment with Cucumis sativus tissue which is a rich source of ascorbate oxidase Based on the quantitative electrolysis of AA A four-channel multipotentiostat for simultaneous measurements with microelectrode arrays. To reduce the complexity of electrochemistry cell, only one reference, and one auxiliary electrode are used Electrocatalytic determination of AA using tetraaza macrocycle-modified electrodes Neutralization of AA in ammonia leading to a change in conductivity...
