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 [BAr F 4] − anion with four fluorinated aryl groups distributed tetrahedrally about a central boron atom. Tetrakis[3,5-bis(trifluoromethyl)phenyl]borate is an anion with chemical formula [{3,5-(CF 3) 2 C 6 H 3} 4 B] −, which is commonly abbreviated as [BAr F 4] −, indicating the presence of fluorinated aryl (Ar F) groups.
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 ...
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 ...
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]
The compound is prepared by the salt metathesis reaction of potassium iodide and potassium tetrachloroplatinate: [3] K 2 PtCl 4 + 4 KI → K 2 PtI 4 + 4 KCl Potassium tetraiodoplatinate is a precursor to the anticancer drug cisplatin .
Using salt metathesis reactions, nitrite, azide, and other small inorganic anions can be obtained with [(Ph 3 P) 2 N] + cations. The resulting salts [(Ph 3 P) 2 N] + NO − 2, [(Ph 3 P) 2 N] + N − 3, etc. are soluble in polar organic solvents. [(Ph 3 P) 2 N] + forms crystalline salts with a range of anions that are otherwise difficult to ...
