Application of 162318-34-5, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 162318-34-5, Name is 5-Ethynyl-2,2′-bipyridine, molecular formula is C12H8N2. In a Article，once mentioned of 162318-34-5
Bipyridyl appended ruthenium alkynyl complexes have been used to prepare a range of binuclear homometallic ruthenium and heterometallic ruthenium – rhenium complexes. The two metal centers are only weakly coupled, as evinced by IR and UV – vis – near NIR spectroelectrochemical experiments and supported by quantum chemical calculations. The alkynyl complexes of the type [Ru(C= Cbpy){Ln}] ({Ln} = {(PPh3)2Cp}, {(dppe)Cp}, {Cl(dppm)2}) undergo reversible one-electron oxidations centered largely on the alkynyl ligands, as has been observed previously for closely related complexes. The homometallic binuclear complexes, exemplified by [Ru(C2bpy-K2-N?N-RuClCp)(PPh3)2Cp] undergo two essentially reversible oxidations, the first centered on the (C2bpy-kappa2-N?N-RuClCp) moiety and the second on the Ru(C?Cbpy)(PPh3)2Cp fragment, leading to radical cations that can be described as Class II mixed-valence complexes. The heterometallic binuclear complexes [Ru(C2bpy-kappa2-N?N-ReCl(CO)3){Ln}] display similar behavior, with initial oxidation on the ruthenium fragment giving rise to a new optical absorption band with Re ? Ru(C?Cbpy) charge transfer character. The heterometallic complexes also exhibit irreversible reductions associated with the Re hetereocycle moiety. (Figure Presented)
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Application of 162318-34-5, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 162318-34-5, in my other articles.
