摘要

研究了在碱性水基溶液中,用铜(III)络合催化剂与氯化钌(III)氧化苯甲醇和2-苯基乙醇。在整个实验过程中,研究人员在溶液中保持恒定的离子强度。他们发现,反应速率与氧化剂、有机底物、催化剂和羟基离子的浓度成正比。然而,当加入外源高碘酸盐时,反应速度减慢。提高溶液的电离电位对反应速率有积极的影响。研究人员计算了各种热性质,如活化能、激活自由能和激活熵,以更好地了解反应的能量学。他们使用红外(IR)和核磁共振(NMR)光谱来识别氧化产物。基于他们的实验发现,他们提出了一个合理的机制来解释所有观察到的现象。这项研究强调了使用简单、经济、环保的方法在铜的+3状态下氧化。这些方法为氧化反应领域的发展提供了新的可能性。

Investigating the Mechanism of Ruthenium (III)-Catalyzed Oxidation of Benzyl Alcohol and 2-Phenyl Ethanol by a Copper (III) Periodate Complex in an Aqueous Alkaline Environment

A study was conducted to investigate the oxidation of benzyl alcohol and 2-phenyl ethanol using a copper (III) complex catalyst with ruthenium (III) chloride in an alkaline water-based solution. The researchers maintained a constant ionic strength in the solution throughout the experiment. They found that the rate of the reaction was directly proportional to the concentrations of the oxidant, organic substrate, catalyst, and hydroxyl ions. However, when external sources of periodate ions were added, the reaction rate slowed down. Increasing the ionized potential of the solution had a positive effect on the reaction rate. The researchers calculated various thermal properties, such as activation energy, activation free energy, and activation entropy, to better understand the energetics of the reaction. They used infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy to identify the oxidation products. Based on their experimental findings, they proposed a plausible mechanism to explain all the observed phenomena. This research highlights the use of simple, cost-effective, and environmentally friendly methods for copper oxidation in its +3 state. These methods offer new possibilities for advancements in the field of oxidation reactions.

期刊介绍: As the leading archival journal devoted exclusively to chemical kinetics, the International Journal of Chemical Kinetics publishes original research in gas phase, condensed phase, and polymer reaction kinetics, as well as biochemical and surface kinetics. The Journal seeks to be the primary archive for careful experimental measurements of reaction kinetics, in both simple and complex systems. The Journal also presents new developments in applied theoretical kinetics and publishes large kinetic models, and the algorithms and estimates used in these models. These include methods for handling the large reaction networks important in biochemistry, catalysis, and free radical chemistry. In addition, the Journal explores such topics as the quantitative relationships between molecular structure and chemical reactivity, organic/inorganic chemistry and reaction mechanisms, and the reactive chemistry at interfaces.
