Abstract:
The discovery of the chemical properties related to the physiological and pathophysiological processes of the nitric oxide molecule has advanced scientific research concerning the control of NO availability in the biological environment. Complexes involving ruthenium and other ligands, such as amine and tetraazomacrocycles, have been used as models because they display properties like stability to air oxidation, solubility in water, and low cytotoxicity against host cells. Given the peculiar properties of nitric oxide, we first conducted a computational experiment based on the molecular orbita

Abstract:
This study investigated the reduction reaction of ruthenium tetroxide by various aliphatic alcohols in acidic medium. UV-Vis spectroscopy still plays an essential role in the analysis and study of volatile ruthenium tetroxide and was used in this study to collect kinetic data. This data was analyzed using graphical and computational methods, such as Mauser diagrams and kinetic simulation software. From the results obtained it is proposed that the reaction occurs by the following two-step reaction model: Ru(VIII) k1 Ru(VI) Ru(VI) k2 k-2 Ru(III) Molar extinction coefficients and conditional rate

Also, a new analogue of complexes of type 1 is reported: the complex (η²-H₂)(isoPFA)Ru(μ-Cl)₂(μ-H)RuH(PPh₃)₂,4, is formed from the reaction of RuCl₂(PPh₃)(isoPFA), 3b, with H₂ in methanol/benzene, and a crystal structure of 4 shows the η²-H₂ ligand; isoPFA and PPFA (see below) are ferrocene based, chelating P-N ligands, with the structu
