Sadler Multidisciplinaria (Ciencias Naturales y Exactas) NADH NADH arene arene NAD + We show that the reaction of Ru II arene chlorido com - plexes of the type [(η 6 -arene)Ru(N,N’)Cl] + arene = p -cymene (p- cym), hexamethylbenzene (hmb), indane (ind), N , N ’ = bipyrimidine (bpm) and 1,10-phenanthroline (phen) with excess sodium formate generates a very stable formate adduct through spontaneous hydroly - sis of the Ru-Cl bond at 310 K and pH* = 7.0. The formate adducts are also produced when Ru II arene pyridine complexes of the type [(η 6 -arene)Ru(N,N’)(Py)] 2+ (where Py = pyridine), are irradiated with UVA (λ irr = 300-400 nm) or visible light (λ irr = 400-660 nm) under the same conditions. The Ru II arene formato adducts do not catalyse the reduction of acetone through transfer hydrogenation. However, all the complexes (except complex 2 which contains phen as the chelat - ing ligand) can catalyse the regioselective reduction of NAD + in the presence of formate (25 mol equiv) in aqueous solution to form 1,4- NADH. The catalytic activity is dependent on the nature of the chelat - ing ligand. Most interestingly, the regioselective reduction of NAD + to 1,4-NADH can be also specifically triggered by photoactivating a Ru II arene Py complex. 2013 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47529964002 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.3 Vol.57 |
