Salt metathesis is a common technique for exchanging counterions. The choice of reactants is guided by a solubility chart or lattice energy. HSAB theory can also be used to predict the products of a metathesis reaction. Salt metathesis is often employed to obtain salts that are soluble in organic solvents.
The salt metathesis reaction route is common. In this method, an alkali metal thiolate is treated with a transition metal halide to produce an alkali metal halide and the metal thiolate complex: LiSC 6 H 5 + CuI → Cu(SC 6 H 5) + LiI. Lithium tert-butylthiolate reacts with MoCl 4 to give the tetrathiolate complex: [3] MoCl 4 + 4 t-BuSLi → Mo ...
Most of this article is about the homogeneous (one-phase) reaction of preformed organolithium compounds: R−Li + R′−X → R−X + R′−Li. Butyllithium is commonly used. Gilman and Wittig independently discovered this method in the late 1930s. [1] It is not a salt metathesis reaction, as no salt is produced.
Metathesis (linguistics), alteration of the order of phonemes within a word Quantitative metathesis , exchange of long and short roles, without changing order of vowel sounds Chemical change in which a pair of molecules exchange electronic patterns of bonding
The low solubility of KClO 3 in water causes the salt to conveniently isolate itself from the reaction mixture by simply precipitating out of solution. Potassium chlorate can be produced in small amounts by disproportionation in a sodium hypochlorite solution followed by metathesis reaction with potassium chloride: [7] 3 NaOCl → 2 NaCl + NaClO 3
Tetrabutylammonium bromide (TBAB) is a quaternary ammonium salt with a bromide commonly used as a phase transfer catalyst. [4] It is used to prepare many other tetrabutylammonium salts by salt metathesis reactions. The anhydrous form is a white solid. [2]
I wouldnt add it, although your observations are insightful. My reasoning: (1) salt metathesis is really intended for salt-like reagents, (2) Wikipedia guidelines urge us not to make it into a textbook. The encylopedia is intended to give and explain facts, but not to go much farther.
RC≡W(O-t-Bu) 3 can react with normal alkynes for metathesis reactions and also with terminal alkynes for both metathesis reactions and polymerizations. [ 6 ] Besides simple metathesis reactions, W 2 (O- t -Bu) 6 also reacts with 3-hexyne in a 1:1 molar ratio to form a triangular tritungsten complex compound [W 3 (O- t -Bu) 5 (μ-O)(μ-CEt)O ...
