AreneOxidationReactivityStructureThe reactivity of M(η 6-arene) 2 derivatives of early transition metals (M = Ti, Cr, Mo, arene = MeC 6H 5; M = V, Nb, arene = 1,3,5-Me 3C 6H 3) has been investigated and the syntheses of new and known compounds are described. The derivatives M...
The anionic (oxygen) redox reaction of NaxTMO2is similar to that of Li-rich Mn-based oxides. The existence of nonbonding O 2pstates is generally recognized to be the origin of anionic redox reaction16,17. For instance, the partial substitution of TMs by Li in Li-rich oxides induces the ...
just as alkaline earth metals, and metalloids have isotopes that often fractionated as a result of chemical transformations, including redox reactions that may be biologically mediated. Thus, there is a wide interest
In this review, redox-induced reactions of π- and σ,π-complexes leading to the selective formation (or cleavage) of C–H, C–C, and C–O bonds have been summarized. To illustrate the synthetic potential of such methodology, the following representative reactions studied in our group are ...
In redox reactions, transition metals can act as both oxidizing agents and reducing agents. This is because they can easily gain or lose electrons due to their variable oxidation states. They also often form colored compounds, making them useful as indicators in redox reactions. How do the oxida...
Transition metals have high density, high hardness, excellent thermal conductivity, perfect electrical conductivity and ductility and they are widely used in various industrial catalysts, photoreactions, redox reactions, etc. For example, Ti has corrosion resistance, excellent mechanical properties, ...
Recent electrochemical investigations of binary mesityl compounds of the early transition metals and of a series of nickel(0) complexes illustrate the influence of the nature and oxidation state of the central atom and of the ligands on the redox behavior. On the basis of macrocyclic nickel(II) ...
While some early experimental challenges had to be overcome (vide infra), second-stage enzymatic reductions were found to be compatible with the presence of metals, such as palladium, copper, rhodium, iron and gold, along with various salts that may have been generated from a prior reaction. ...
Transition metals (e.g., copper and iron) are essential in most biologic reactions, including DNA, ribonucleic acid (RNA), andprotein synthesis, as well ascofactorsof numerousenzymes. However, the accumulation of redox-active transition metals in tissues in excess of the capacity of cellular prot...
The metals are generally in the form of nanoparticle, and the weight ratios to the 2D TMO&Cs are optimized to avoid the surface overloading effect. In addition to the “electron sink” effect, some of the noble metal nanostructures exhibit localized surface plasmon resonance in the visible ...
