-More on double replacement from Wikipedia September 2019 "Salt metathesis reaction"
A salt metathesis reaction, sometimes called a double replacement reaction, double displacement reaction, is a chemical process involving the exchange of bonds between two non-reacting chemical species which results in the creation of products with similar or identical bonding affiliations.[1] This reaction is represented by the general scheme:
A-B + C-D → A-D + C-B
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. Illustrative is the conversion of sodium perrhenate to the tetrabutylammonium salt:[2]
NaReO4 + N(C4H9)4Cl → N(C4H9)4[ReO4] + NaCl
The tetrabutylammonium salt precipitates from the aqueous solution. It is soluble in dichloromethane.
Salt metathesis can be conducted in nonaqueous solution, illustrated by the conversion of ferrocenium tetrafluoroborate to a more lipophilic salt containing the tetrakis(pentafluorophenyl)borate anion:[3]
[Fe(C5H5)2]BF4 + NaB(C6F5)4 → [Fe(C5H5)2]B(C6F5)4 + NaBF4
When the reaction is conducted in dichloromethane, the salt NaBF4 precipitates and the B(C6F5)4- salt remains in solution.
Metathesis reactions can occur between two inorganic salts when one product is insoluble in water. For example, the precipitation of silver chloride from a mixture of silver nitrate and cobalt hexammine chloride delivers the nitrate salt of the cobalt complex:
3 AgNO
3 + [Co(NH3)6]Cl3 → 3 AgCl + [Co(NH3)6](NO3)3
The reactants need not to highly soluble for metathesis reactions to take place. For example barium thiocyanate forms when boiling a slurry of copper(I) thiocyanate and barium hydroxide in water:
Ba(OH)
2 + 2CuCNS → Ba(CNS)
2 + 2CuOH
