Organometallic complexes supported on a metal-oxide cluster. pH-dependent interconversion between the monomeric and dimeric species of the polyoxoanion-supported [(arene)Ru]2+ complex
Keggin polyoxometalate (POM)-supported two (arene)Ru2+ complexes, i.e., the monomeric species (type-m) [{(arene)Ru(H 2O)}PW11O39]5- and the dimeric species (type-d) [({(arene)Ru}PW11O39)2(mu- WO2)]8-, were prepared as water-soluble Et 2NH2+ salts by pH-controlled reactions in aqueous solutions of the in situ-generated, mono-lacunary Keggin POM [PW 11O39]7- with the organometallic precursor [{RuCl2(arene)}2]. The effects of the arene (benzene (1), toluene (2), p-cymene (3), and hexamethylbenzene (4)) on the proportion of the type-m to type-d complex produced were examined. pH-Varied 31PNMR spectroscopy showed that there was a pH-dependent interconversion between type-m and type-d complexes, i.e., the ratio of the dimeric species increased as pH of the solution was lowered. Under the reaction conditions, the dimeric species d1, d3, and d4 as water-soluble Et2NH2+ salts were successfully isolated as the major products. It was concluded that (1) steric repulsion between the two (arene)Ru2+ fragments in the dimeric species was not significant, (2) the proportion was strongly dependent on the pH of the solution rather than the bulkiness of the arene, and (3) the use of the in situ-generated [PW11O39]7-, but not the isolated lacunary species, such as K7[PW11O 39]¡¤nH2O, had an effect on the reaction.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 37366-09-9 is helpful to your research., Reference of 37366-09-9
