| Abstract | Dichloro or chloro ruthenium(III) complexes with polyaminopolycarboxylato ligands were synthesized (ligands: ethylenediaminetetraacetate (edta), N,N-dimethylethylenediamine-N,N'-diacetate (N,N'-Me(2)edda), and nitrilotriacetate (nta)). Magnetic moments of these ruthenium(III) complexes are about 2. So they are low spin complexes. The oxidation of olefines (cyclohexene, styrene or 1-hexene) catalyzed by these ruthenium(III) complexes in the presence of hydrogen peroxide has been studied: catalyst, polyaminopolycarboxylatoruthenium(III) complex (1.0 x 10(-3) mol dm(-3)); substrate, olefin (0.2 mol dm(-3)); co-oxidizing reagent, hydrogen peroxide (0.75 mol dm(-3)); solvent, 1,4-dioxane-water (1:1 (v/v)). The chloro Hedta ruthenium complex ([RuCl(Hedta)](-)) was the most effective catalyst for the oxidation under these conditions. The main product of this reaction was diol (yield:48%, 1,2-cyclohexanediol; 68%, 1-phenyl-1,2-ethanediol; 6.5%, 1,2-hexanediol). Since UV/visible spectrum of the edta complex in the presence of hydrogen peroxide shows the formation of the oxoruthenium(V) complex, the oxoruthenium(V) species is supposed to be the active species. |
