The ability of [RuII(tButpy)(dmbpy)(MeCN)]2+ (1-MeCN) to capture CO2, with the assistance of triethanolamine (TEOA), has been assessed under photocatalytically-relevant conditions. The photolability of 1-MeCN has proven essential to generate a series of intermediates which only differ by the nature of their monodentate ligand. In DMF, ligand photoexchange of 1-MeCN to give [RuII(tButpy)(dmbpy)(DMF)]2+ (1-DMF) proceeds smoothly with a quantum yield of 0.011. However, in the presence of TEOA, this process was disrupted, leading to the formation of a mixture of 1-DMF and [RuII(tButpy)(dmbpy)(TEOA)]+ (1-TEOA). An equilibrium constant of 3 was determined Interestingly, 1-TEOA demonstrated an ability to reversibly catch and release CO2 making it a potentially crucial intermediate towards CO2 reduction4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Category: pyridine-derivatives) was used in this study.
4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6) is used in the synthesis of a series of o-phenanthroline-substituted ruthenium(II) complexes.Category: pyridine-derivatives Furthermore, 4,4′-Dimethyl-2,2′-bipyridine is used as a chemical Intermediate. It can be used for the determination of ferrous and cyanide compounds.
