Mn-MeTACN complexes have been studied extensively by ESI-MS in the oxidation of a variety of organic substrates using hydrogen peroxide (MeTACN = 1,4,7-trimethyl-l, 4,7-triazacyclononane). An assortment of binuclear and mononuclear species has been observed [7,33,34]. One such example focused on the use of these complexes for the oxidative drying of alkyd paints. The binuclear... 

Ru-1,4,7-trimethyl-1,4,7-triazocyclononane complexes czs-[Ru( 1,4,7-trimethyl-l,4,7-triazacyclononane)(02)(CF3C02)] with fert-BuOOH [20,21] also afforded reasonable results and recently this complex was heterogenized on silica [50]. In contrast to the homogeneous catalyst, this heterogeneous ruthenium complex in epoxidation of cyclohexene produced cyclohexene oxide in 75% yield with cyclohexen-l-one in 14% yield, while the homogeneous catalyst produced cyclohexen-l-ol and cyclohexen-l-one mainly. Examples of... 

Dimeric complexes of the V02 group have single 0x0-bridges giving a [O2V-O-VO2] core such as in [L2V204(/x-O)] (L = 1,4,7-trimethyl-1,4,7-triazacyclononane), or a rare type of dioxo bridge as seen in the compound shown in (10). In this compound, the p-O distances are asymmetric, as indicated, the shorter being about 1.675 A and the other around 2.27 A.

Cohydrolysis of MnLCls (L= 1,4,7-triazacyclononane) and RuL Cl3 H20 (L = 1,4,7-trimethyl-1,4,7-triazacyclononane) in equimolar amounts in methanol containing an excess of sodium acetate gives rise to the asymmetric heterodinuclear species [L Ru(/i-0)(/u-CH3C00)2MnL]PFg on addition of sodium hexafluorophosphate. A model to interpret the strong spin-exchange coupling in this complex was presented." ...
