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 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.
The reaction is driven by the low solubility of potassium chlorate in water. The equilibrium of the reaction is shifted to the right hand side by the continuous precipitation of the product (Le Chatelier's Principle). The precursor sodium chlorate is produced industrially in very large quantities by electrolysis of sodium chloride, common table ...
The Petasis reagent is prepared by the salt metathesis reaction of methylmagnesium chloride or methyllithium [2] with titanocene dichloride: [3] Cp 2 TiCl 2 + 2 CH 3 MgCl → Cp 2 Ti(CH 3) 2 + 2 MgCl 2. This compound is used for the transformation of carbonyl groups to terminal alkenes. It exhibits similar reactivity to the Tebbe reagent and ...
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]
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 ...
