Alkali metals magnesium

Some metals, which are difficult to deposit electrolytically from aqueous solutions, can be deposited from appropriate 11011-aqueous solutions. They are, for example, alkali metals, magnesium, and aluminum. They are usually deposited at more negative potentials than the reduction of water. The electrodeposition of lithium... [Pg.324]

Intermetallic and Semiconducting Compounds. Indium forms intermetallic compounds with a great many metals and combinations of metals including alkali metals, magnesium, the iron group, rare earths, and precious metals such as the platinum group. Carbon-free indium-based... [Pg.81]

Firstly, the reaction with alkali metals, magnesium or other similarly reactive metals, mostly in ethereal solution. The tendency toward formation of the metal halide is the probable driving force of the reaction. Secondly, the reaction with silicon metal at about 1000 °C. This type is called a transport reaction because silicon metal is transported in the gaseous phase ... [Pg.103]

E R. E. Mulvey, s-Block metal inverse crowns synthetic and structural synergism in mixed alkali metal-magnesium (or zinc) amide chemistry. Chem. Commun. 1049-56 (2001). [Pg.459]

Previously we calculated the electronic states of molten chlorides of alkali metals, magnesium and zinc ) as well as molten Si02 ), and found that the mechanism of formation of complex ions and their polymerization, and also the viscosity can be well explained in terms of... [Pg.286]

Compounds R3S11M, where M is an alkali metal, magnesium, zinc, or cadmium, (Sections 19.1, 19.2 and 19.7) often behave as though they are in equilibrium with RM and R2Sn , as shown in Scheme 21-2.13 14... [Pg.352]

Noncombnstible liqnid. EDB reacts vigor-onsly with alkali metals, magnesium, aluminum caustic alkalies and strong oxidizing substances. [Pg.453]

Every chemist who has performed a reaction with a metal has observed that the spontaneous reaction is not the general rule. Even relatively strong reductors, (alkali metals, magnesium, aluminum) frequently react sluggishly after an induction time because of the presence of surface impurities which inhibit the reaction. This phenomenon is known as "passivation". [Pg.168]

The composition of the solvent has a dramatic influence on the electrodeposition process of refractory metals in fused electrolytes [1]. Also, in contrast to other metals prepared by electrolysis at high temperatures such as alkali metals, magnesium or aluminium, all the refractory metals exist in a variety of oxidation states. The metal chlorides undergo disproportionation reactions leading to formation of seemingly colloidal metal in the melt. The... [Pg.159]

Alkylating agents that have been used include organo compounds of alkali metals, magnesium, aluminum, mercury, and zinc. The following equations illustrate some examples ... [Pg.158]

After almost half century of intensive, fundamental, and fruitful investigations of enolate structures, there is now clear evidence indicating that enolates of groups 1, 2, and 13 metals - lithium and boron being the most relevant ones - exist as the O-bound tautomers 1 the same holds in general for silicon, tin, titanium, and zirconium enolates [4]. Numerous crystal structure analyses and spectroscopic data confirmed type metalla tautomer 1 to be the rule for enolates of the alkali metals, magnesium, boron, and silicon [5]. [Pg.2]

Although many transition metal complexes containing T) -bonded substituted acetylides are known, few are available in more than moderate yields via conventional reactions of metal halides with an anionic aUcynyl compound of an alkali metal, magnesium, or copper(I) or hy dehydrohalogenation in a reaction between the metal halide and a 1-alkyne. More recently, reactions between many 1-alkynes and RuCl(l Ph3)2(Tj -CsHs) have been shown to give cationic vinylidene complexes, which are readily deprotonated to give the corresponding substituted Tj -acetylides. The synthesis of the phenylethynyl derivative is typical the intermediate phenylvinylidene complex is not isolated. [Pg.82]
